The Speciality of Split-Point Drill Bits

When selecting a drill bit, there are various factors which determine which drill bit will be best for an application, including the type of material to be drilled, the speed of drilling, and the desired number of holes per bit. As such, you need to select one with the right combination of material, finish, length, and style that will be best suited for your job.

Drill bits are generally classified as Twist Drill, Counterbore, Countersink, Flat Bottom Boring, and Specialty. Out of these, twist drill bits are the most common type and are used for everyday drilling in all types of material. However, they can be quite confusing considering the sheer variety in length, tip, and material specifications.

The length of a twist drill has much to do with its rigidity - a shorter bit will be stronger and less likely to wander or break but may not have the reach needed for all jobs. The length of a twist drill is directly correlated to its rigidity - the shorter the length the stronger the bit and the less likely it is to break and vice versa. Common twist drills are available in fractional inch, wire sizes, letter sizes, and metric decimal millimetre with Guhring tools. Twist drills for use in automated machinery are only available in fractional inch and decimal millimetre. Twist drills are available in different tip styles, one of the most popular tips used for wood drilling is Split Drill Point bit. A split drill point comes with an advanced drill point that prevents ‘walking’ and provides improved penetration with less effort.

What is walking?

The tip of a regular drill bit is smooth with a slightly protruding point as if a lightly pointed skull cap. Let’s say you are drilling a hole into a plank of wood for building a precise furniture piece. If the wood surface is smooth, this rounded tip can slip off the exact point and shift its target, creating a hole right next to it. This phenomenon of shifting of target point is called walking.

How Split-Point Drill Bits avoid walking?

Split-point bits are highly effective against walking. The shaft of a quality split-point bit features three grooves that lift away debris, allowing you to drill holes faster and with lesser snags. These grooves continue to the tip of the bit, where they cut into the tip's cap, breaking the smooth surface. This creates a grooved bit tip that conveniently anchors itself into the wood and keeps your bit on target. Available in 118 or 135-degree angles, split point drill bits are better for drilling in curved surfaces or alloy steels.

Maximize power transmission efficiency with Poly V-Belt Drives.

Belt drives have played an integral part of every machining industry since the beginning of the industrial revolution. With the introduction of V-Belt drives, power transmission efficiency has been improved drastically. They have become a default standard in the industrial tool supply domain.

Furthering the technological evolution are Poly V-Belts. An invention in the belting landscape that is driving productivity, affordability and machine efficacy to the next level.

Poly V-Belt- The belt for all applications

Poly V-Belts are made from a single block of polymer, designed with multiple v shaped longitudinal ribs. The V shaped ribs are designed to run on a pulley with corresponding grooves, which the ribs fit neatly into. The belt transmits torque by contact of the belt rib flanks and the pulley grooves. A polyester cord runs through the belt, along with a rubber backing that protects the cord and the radial stability of the belt. This unique design combination allows the Poly V-Belt to counter-bend, enabling a single belt to drive several accessories from both sides of the belt.

Fenner- A trusted name in India

Fenner is a highly reputed manufacturer of all types mechanical power transmission products. Fenner belts, V-belts, Poly V-Belts, Pulleys, Couplings and Gear Boxes have become the industry bench-marks over the years, as they are designed and manufactured in state-of-art facilities. Every Fenner Belt adheres to the Indian quality standards; ISO-9001:2000 & ISO/TS-16949:2002 along with ISO 14001:1996

How Poly V-Belts work their magic?

Poly V Belts have a multitude benefits when it comes to boosting power transmission efficiency.

Here are 5 benefits that will give you some perspective on the potential of Poly V-Belts:

1. Compactness- Due to its compact size, a Poly V-Belt can operate at a minimum pulley diameter of just 9mm, compared to a minimum pulley diameter of 50mm with a traditional V-belt.

2. Reduced Noise- Thanks to the mono-block design, a Poly V-Belt produces negligible noise and vibrations during its operation. Also unlike regular V-Belts, there is no need to match belts, thereby reducing maintenance and eliminating belt differential ‘flapping’.

3. Even Load Distribution- Poly V-Belts are flat cord-reinforced transmission Belts with length-wise running triangular-shaped ribs with a top angle of 40 degrees. This construction leads to better support for all cords in the reinforcement and therefore, an even load distribution is achieved.

4. High-Output- As per iso-tension and iso-geometry technical tests, Poly V-Belts can achieve over 98 percent higher outputs than regular V-belts, thereby allowing drastic reductions in engine size.

5. Improved Transmission Ratio- As Poly V-Belts require lesser areas; improved transmission is also possible. Poly V-Belts can achieve ratios of 1:60, as compared to 1:20 for regular V-Belts.

Poly V-Belts are conquering every industrial domain due to their unparalleled performance. Some of the industries relying on Poly V-Belts include; Aerospace, Mining, Automotive, Refrigeration and elevators.

Apart from Poly V-Belts, MKIS also provides provide Fenner Round belts, Wedge-V belt, NuTLink V-Belt, SuperTLink wedge belts and special beltings, all delivered as per specific customization requirements.

How to Drill Through Stainless Steel Using the Right Drill Bit

Drilling through stainless steel is similar to drilling through any other type of metal, albeit with a few key differences. In this article, we explain how to drill in stainless steel using Guhring tools. For this purpose, using high-speed drill bits such as carbide drills or gun drills are preferable. But using the right kind of drill is simply the first step, you also have to have the skills and knowledge to successfully drill through stainless steel. One would already know that drilling through stainless steel is different from drilling mild steel, even though the basic technique is much the same. Here’s how to get those holes drilled without ruining your drill bits.

Before we begin with the procedure, it would help to first know what stainless steel actually is. Stainless steel is a metallic material which is noted for its purity. There is alloyed and unalloyed steel, but only the alloyed variant can be stainless.

Equipment you will need:

• A Drill Bit (of course!)
• Eye Protection Gear
• Ear Defenders or Ear Plugs
• Cutting Fluid which includes oils, oil-water emulsions, pastes, gels, etc
• Heavy Duct Tape
• A Marker Pen or 3 Corner Pyramid Punch
• Sturdy Clamp
• Felt or Plastic to protect the workpiece in the clamp.

Procedure to Drill Stainless Steel

1. Firstly, steer yourself clear of all loose and hanging items such as loose clothing, uncovered hair, or even gloves. You don’t want them to get stuck into the spinning drill.
2. Mark the position of the hole with a marker pen or tap a small indent with a 3-corner pyramid punch.
3. Use heavy-duty tape to mask the area around your mark to avoid the chips from scratching the surface as they spin
4. For drilling a metal less than 3mm thick, you can use a single bit to achieve the desired size hole. In the case of thicker metal, it is recommended to start with a bit half the size of the desired hole diameter for an initial hole and then step up to the final size drill for second drilling.
5. Secure the workpiece into position by firmly clamping it.
6. Put a few drops of lubricating oil into the depression you made with the center punch. Using cutting fluid will help to clear the swarf away from the drill bit to reduce the risk of becoming friction welded and reduces work hardening. Coolant can be sprayed, dripped, or flooded, but it is important to use a generous amount that ensures good contact between the fluid and the tool interface.
7. Put on your safety gear and hold your drill perpendicular to the bracket, insert the tip of the bit into the punched hole and begin to drill.
8. Once the hole has been made, do not immediately touch the bit or the hole as it will be hot enough to cause a serious burn. Wipe the coolant with care off the metal as the swarf held in the coolant may scratch the surface.

Choosing the Right Drill Bit

There are various types of Guhring drills bit and reamers suitable for drilling stainless steel. Choosing the right one for your task is what matters to get the best results.

• HSS or High-Speed-Steel bits are designed for use on stainless steel and can be used for hand and machine drilling. It is recommended to use an HSS bit that is TiN tipped as the Titanium Nitride reduces friction which in turn reduces work hardening caused by excessive heat and minimizes flank and crater wear.
• Carbide drills provide faster cutting rates, longer tool life, better positional and dimensional accuracy, and improved surface finish. Shorter cycle times and tighter tolerances translate into maximum machine utilization, better part quality and optimum hole making cost savings.
