19/32" HSS Black Oxide Drill Bit

This 19/32 inch jobber-length drill bit is made from high-speed steel with a black oxide finish for abrasion resistance. It features a 118-degree conventional point and a round shank compatible with standard tool-holding systems. The bit is designed for general-purpose drilling in a variety of materials.

Suited for production and maintenance tasks

This drill bit suits machinists, maintenance technicians and DIY users who need a reliable bit for portable or stationary drilling in aluminum, brass, copper, metal, plastic and wood. It is not intended for buyers who require specialised geometry for hardened steel, deep-hole drilling or high-volume production with carbide tooling.

118-degree conventional point angle

The 118-degree point determines how the bit starts and cuts in common materials, making it the key specification for matching the tool to the job. This angle provides a balance of centring ability and chip evacuation for the listed workpiece materials.

Questions about this item

How do I install the 19/32" HSS drill bit and what step do people often get wrong?

Insert the round shank fully into the chuck and tighten securely; the common mistake is not seating the shank completely, which causes run-out and premature wear.

What maintenance or replacement will the 19/32" black oxide bit need later?

Resharpen the 118° conventional point when cutting slows; replace the bit once the flutes wear down or the black oxide coating no longer protects against abrasion.

What limit appears first on the 19/32" jobber bit under sustained drilling?

Heat buildup at the 118° point dulls the edge fastest, especially in harder metals, forcing you to stop and cool or resharpen before the shank or flutes fail.
