Import 20922 Mechanics Drill Bit 13/32 Inch Hss

Product Description

The IMPORT 20922 is a mechanics-length twist drill bit designed for general-purpose metal drilling in trade and industrial applications. Built from high-speed steel with an oxide finish, this bit features a 135-degree split point that reduces walking on contact and allows drilling without a center punch in most situations. The Weldon flat shank with three flats provides positive drive engagement and prevents slippage in compatible chuck holders. At 0.4062 inches (13/32 inches) in diameter with an overall length of 4.375 inches and a flute length of 2.8125 inches, it fits standard drill press and hand-drill setups used by machinists, pipefitters, and HVAC technicians.

This drill bit is suited for right-hand cutting into a range of ferrous metals including carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The mechanics-length body keeps the bit compact and rigid for drilling in tight clearances or through flanges and brackets. It is a practical fit for HVAC equipment mounting, conduit and bracket work, plumbing rough-in, and general sheet metal or structural steel tasks where controlled, clean-entry drilling is needed.

Key Features

• 135-degree split point reduces drill walk and enables clean entry without center punching
• High-speed steel construction handles ferrous metals including stainless and high alloy steel
• Weldon flat shank with three flats prevents bit rotation and slippage under torque
• Oxide finish provides mild lubricity and corrosion resistance during storage and use
• Web-thinned, parallel web configuration reduces thrust requirements during drilling
• Mechanics-length body offers added rigidity compared to jobber-length bits

Compatibility

Designed for use with drill presses, magnetic drills, and hand drills equipped with Weldon-style chuck holders or set-screw collets that accept a 13/32 inch diameter shank. Suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces.

Installation Notes

This bit is installed by a machinist, pipefitter, or general tradesperson using a Weldon-compatible chuck or collet; verify the chuck's set screws engage the flats securely before applying load. Always wear appropriate eye protection and secure the workpiece before drilling. Use cutting fluid or lubricant when drilling stainless steel or high alloy materials to extend tool life and reduce heat buildup. Do not exceed the rated speed for the bit diameter and material being drilled.
