Westward 1/2 inch HSS mechanics drill bit, 135 degree point, black and gold finish

Westward

Westward 1/2 in 135° HSS Mechanics Drill Bit

SKU CH-2RZG-4CKQT

A 1/2 in high-speed steel mechanics drill bit with a 135-degree point for efficient drilling in metal and wood

  • 135° split point starts on contact without walking
  • High-speed steel body resists heat during extended drilling
  • Black-and-gold surface finish reduces friction and chip welding
  • Fractional 1/2 in diameter fits standard chucks directly
  • Mechanics-length flute clears chips efficiently in deep holes

135° HSS Mechanics Drill Bit

This 1/2 inch mechanics drill bit is made from high speed steel with a black and gold finish. It uses a 135 degree point angle suited for general purpose machining in metal. The fractional inch measurement system provides standard sizing for workshop tasks.

Thermals noise and power draw

As a non-powered cutting accessory, this drill bit generates no electrical noise or power draw during use. Heat produced while drilling depends on the workpiece material, cutting speed, and the coolant or lubrication applied by the operator.

Black and gold finish benefits

The black and gold surface treatment helps identify the tool and provides a layer of corrosion resistance during storage. It does not alter the fundamental cutting geometry or the high speed steel substrate performance in machining applications.

Questions about this item

How do I install the 1/2 in drill bit and what step is often missed?

Insert the 0.5000 in shank fully into the chuck and tighten all three jaws evenly; the step people miss is not securing the bit deep enough, which causes wobble at 135 degree cutting angles.

What maintenance or replacement will this HSS mechanics drill bit need later?

The high speed steel cutting edges dull with use; plan to resharpen the 135 degree point angle or replace the bit once it no longer cuts cleanly in steel.

What limit shows up first when drilling continuously with this 1/2 in bit?

Heat builds rapidly in the high speed steel body during sustained drilling; the bit loses hardness and cutting efficiency before any other mechanical limit is reached.
