Import -20920-5 Mechanics Drill Bit 3/8 in Hss Split Point

Product Description

The IMPORT -20920-5 is a mechanics-length drill bit designed for drilling into ferrous metals and hard alloys in trade and industrial applications. It features a 3/8-inch diameter with a 135-degree split point geometry that reduces walking on contact, eliminating the need for a center punch on most surfaces. The bit is manufactured from high-speed steel (HSS) with an oxide finish for added surface hardness and corrosion resistance. A three-flat Weldon shank provides positive drive engagement in compatible chucks, preventing slippage under load. Right-hand cut spiral flutes evacuate chips efficiently during drilling operations.

This drill bit is suited for use on carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel. The mechanics length format — shorter than a jobber bit — gives machinists and maintenance techs better rigidity in tight clearance situations. It is a general-purpose bit appropriate for machine shop work, maintenance drilling, HVAC bracket fabrication, and structural steel work where controlled hole entry and chip clearance are priorities.

Key Features

• 135-degree split point reduces drill walk and lowers required feed force on hard materials
• High-speed steel construction handles carbon steel, stainless steel, cast iron, and high alloy materials
• Three-flat Weldon shank locks securely in compatible drill chucks to prevent rotation slip
• Oxide coating adds surface hardness and mild corrosion protection
• Web-thinned, parallel web configuration improves cutting efficiency and reduces thrust
• Right-hand spiral flute design provides effective chip evacuation during through-hole drilling

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with machine tools, drill presses, and hand drills equipped with a Weldon flat chuck or collet system accepting a 3/8-inch Weldon shank.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with drilling operations on ferrous metals. Secure the workpiece firmly before drilling to prevent movement. Use appropriate cutting fluid or coolant when drilling stainless steel or high alloy materials to reduce heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
