Import -20870-P Mechanics Drill Bit Letter P Hss Split Point

Product Description

The IMPORT -20870-P is a Letter P mechanics drill bit designed for general-purpose metal drilling in trade and industrial applications. Built from high-speed steel with an oxide finish, it features a 135-degree split point that reduces walking and cuts faster than a standard 118-degree tip. The Weldon flat shank with three flats provides a positive drive connection and resists slipping in the chuck. At 0.3230 inches in diameter and 4.0625 inches overall length, this bit handles a wide range of ferrous metal drilling tasks. Licensed tradespeople and machinists working in fabrication, mechanical, or maintenance settings will find it a practical general-purpose option.

This bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and other ferrous materials in mechanical and maintenance applications. The mechanics length profile balances rigidity and reach for use in standard drill presses, milling machines, and hand drills. The spiral flute and web-thinned, parallel web configuration promote chip evacuation and reduce cutting resistance in tougher alloys. It is sold individually with a minimum order quantity of 3 units.

Key Features

• Letter P diameter — 0.3230 inches for precise hole sizing
• 135-degree split point reduces drill walk and lowers cutting force
• High-speed steel construction handles ferrous metals including stainless steel and high alloy steel
• Weldon flat shank with 3 flats prevents chuck slippage under torque
• Web-thinned parallel web improves chip clearance and reduces thrust
• Oxide finish provides mild lubricity and corrosion resistance during storage

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with standard Weldon flat chuck holders and drill presses, milling machines, and hand drills that accept a Weldon shank. Suitable for carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and similar ferrous workpiece materials.

Installation Notes

Secure the Weldon flat shank firmly in a compatible chuck or tool holder, ensuring at least one flat engages the set screw to prevent rotation. Always secure workpieces before drilling and use appropriate cutting fluid when working with stainless steel or high alloy materials to extend tool life. Wear appropriate PPE including eye protection when operating any rotating cutting tool. Inspect the cutting edges before each use and replace if chipping or dullness is observed.
