Solid Carbide Jobber Bit for Abrasive Materials

This solid carbide jobber drill bit targets machinists and maintenance teams who need to bore abrasive workpieces such as cast iron, high-silicon aluminium, bronze, copper alloys, hard rubber or plexiglass while maintaining hole accuracy at elevated temperatures.

31/64 inch Diameter with 3 inch Flute Length

The 31/64 inch cutting diameter and three inch flute provide enough reach for medium-depth holes in the listed materials, yet the brittle carbide substrate will chip or fracture if subjected to heavy interruption, hand-held use or insufficient rigidity in the setup.

Uncoated Bright Finish and 118 Degree Point

The uncoated bright finish and conventional 118 degree point geometry deliver immediate centering and chip evacuation in non-ferrous and abrasive stock without the added cost or thickness of a coating layer.

Highlights

  • Uncoated bright finish suits high-temperature drilling applications
  • 118-degree conventional point handles cast iron and non-ferrous alloys
  • Round shank fits standard drill chucks securely

Questions about this item

Will the 31/64" solid carbide bit fit the round-shank chuck on my older drill press?

Yes — the round shank is a standard interface that matches most drill-press chucks, so the bit seats securely in older machines.

How can I confirm the 118-degree point is cutting correctly after I install the bit?

Run a test hole in scrap material; a clean, round hole with minimal burr and consistent chip evacuation shows the point geometry is working as intended.

Does the single-pack include any coating or holder, or must I buy those separately?

The pack contains only the uncoated bright-finish drill bit; no coating, case or holder is included, so purchase any accessories you need on their own.
