Import -20914-10 Mechanics Drill Bit 9/32 in Hss

Product Description

The IMPORT -20914-10 is a mechanics-length twist drill bit designed for general-purpose metal drilling in production and maintenance applications. The bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard or smooth surfaces. Constructed from high-speed steel with an oxide finish for basic corrosion resistance, this bit handles a range of ferrous materials. The Weldon flat shank with three flats provides a positive grip in compatible chucks, preventing slippage under torque. Spiral flutes with a parallel web and web-thinned geometry aid chip evacuation during drilling.

This drill bit is suited for use in machine shops, maintenance facilities, and fabrication environments where drilling into carbon steel, cast iron, high alloy steel, stainless steel, and high tensile strength alloy is routine. The mechanics-length body offers a compact overall length of 3.75 inches, making it practical for confined work areas or drill press applications where a jobber-length bit would be excessive. A flute length of 2.25 inches provides adequate depth capacity for most structural and plate stock applications. This item is sold individually but requires a minimum order quantity of 10 units.

Key Features

• 135-degree split point for self-centering and reduced walking on workpiece surfaces
• High-speed steel construction suitable for ferrous metal drilling
• Weldon flat shank with three flats prevents slippage in compatible tool holders
• Web-thinned, parallel web geometry improves chip clearance and reduces thrust requirements
• Oxide finish provides basic surface protection
• Mechanics-length design offers a compact 3.75-inch overall length for restricted-access applications

Compatibility

Compatible with drilling into carbon steel, cast iron, high alloy steel, high tensile strength alloy, and stainless steel. Requires a drill chuck or tool holder accepting a Weldon flat shank.

Installation Notes

Install into a compatible Weldon shank chuck and verify the set screws are properly engaged against the flats before operation. Ensure the workpiece is securely clamped before drilling to prevent movement. Use appropriate cutting fluid or coolant when drilling stainless steel or high alloy steel to extend bit life. Inspect the cutting edges for wear or damage before each use and replace bits that show chipping or dullness.
