3/8-inch HSS drill bit

This extra-long high-speed steel bit has a 118-degree conventional point and a black oxide finish. It is manufactured for general-purpose machining and measures 3/8 inch in diameter. The design targets tradespeople and DIY users who need deeper reach in a single pass.

Black oxide coating and 28-degree helix

The black oxide surface reduces friction and resists corrosion during extended use. A 28-degree helix angle clears chips efficiently so the bit does not bind in deep holes. It fits any standard drill chuck that accepts a 3/8-inch shank, freeing the operator from frequent bit changes.

Maximum drilling depth 7 1/2 inches

The flute length supports a maximum drilling depth of 7 1/2 inches, roughly four times the bit diameter. This covers most through-hole tasks in wood, plastic and mild steel without requiring an extension. Very thick workpieces or production-volume drilling will exceed the practical reach of this single bit.

Questions about this item

How deep can the 3/8 inch bit drill before it bottoms out?

The flute length allows a maximum drilling depth of 7 1/2 inches, which is the practical limit before chip evacuation becomes difficult.

Does the high-speed steel hold its temper when the bit runs hot in a production job?

The HSS body with black-oxide finish resists heat buildup during extended drilling, keeping the cutting edges hard enough for general-purpose machining.

What shank style does the bit need so it locks into my drill chuck?

It has a standard 3/8 inch round shank that fits any three-jaw chuck rated for that capacity.
