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.
Aerox HSCO8 Split Point Drill
The HSCO8- Split point drill from Guhring drills
comes with a 135` split point for
accurate drilling without punching or centring. This reduces radial forces,
small hole tolerances, and minimal feed forces. The flutes are specially formed
for reliable chip formation and evacuation. It comes with a heavily reduced
tapered web for additional tool rigidity while maintaining minimal forces. The
bit is built using cobalt and surface finished with bronze oxide for improved
tool life and high thermal resistance.
