Cle-Line C23850 Mechanics Length Drill Bit 3/8 in 135 Degrees

SKU CH-3WQQ-X4WRE

A 3/8 in mechanics length drill bit with a 135-degree point angle and high-speed steel construction

  • Mechanics length for easier access in tight spaces
  • 135-degree split point starts on contact without wandering
  • High-speed steel construction resists wear during repetitive drilling
  • Black and gold surface finish reduces friction and heat buildup
  • 3750 inch fractional size matches standard 3/8 inch chucks

Cle-Line 3/8 in Mechanics Drill Bit

The Cle-Line C23850 is a mechanics-length drill bit manufactured from high-speed steel with a black and gold finish. It features a 135-degree point angle and a fractional-inch measurement of 0.3750. This accessory is intended for general machining tasks using power or pneumatic tools.

Suited for general workshop drilling

This bit suits machinists and maintenance technicians who need a standard 3/8-inch fractional tool for everyday metalworking. It is not intended for buyers who require specialised coatings, carbide construction or non-fractional metric sizing.

135-degree point angle

The 135-degree point angle determines how the bit engages the workpiece and influences chip formation in steel. Verify that this angle matches the material and drilling conditions before purchase.

Questions about this item

How do I install this 3/8 inch bit in my drill chuck, and what step causes slippage?

Open the chuck fully, insert the shank straight until it seats, then tighten each jaw evenly; the step people get wrong is tightening only one side, which leaves the bit off-centre and causes run-out.

What maintenance or replacement will this high-speed steel bit need later?

The cutting edges will dull with use; resharpen the 135-degree point on a bench grinder or replace the bit when the web thickness wears below the flute depth.

What limit appears first when drilling steel continuously with this fractional-inch bit?

Heat buildup at the tip softens the high-speed steel, so cutting speed drops before the shank or flute geometry becomes the bottleneck.
