Drill bit for general-purpose metalwork
This Westward jobber-length drill bit is made from high-speed steel with a black oxide finish. It measures 1/2 inch in diameter with a decimal equivalent of 0.5000 and features a 135 degree split point designed for self-centring and reduced thrust.
Suited for machinists and maintenance technicians
The 135 degree geometry suits harder materials such as stainless steel and alloy steels where a sharper point would dull quickly. Users who primarily drill soft aluminium, wood or plastics may find a different point angle more efficient for those materials.
The 135 degree split point decides the application
This point angle and split-point design determine how the bit engages the workpiece and evacuates chips. Match the angle to the material hardness and the drilling conditions to avoid premature wear or walking.

Questions about this item
Which drill bit size matches the 1/2 in specification?
The 1/2 in jobber length bit with decimal equivalent 0.5000 is the only size offered for this model.
What does the 135 degree point angle do in use?
The 135 degree split point centres the bit quickly and reduces walking on hard materials.
How does the black oxide finish affect drilling?
Black oxide on high speed steel adds lubricity and corrosion resistance for longer bit life.
