Import 20801 Mechanics Drill Bit 0.228 in Hss Split Point

Product Description

The IMPORT 20801 is a mechanics-length high-speed steel drill bit designed for general-purpose hole-making in ferrous and hard metal workpieces. The 0.228-inch diameter bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. A right-hand spiral flute with web-thinned geometry clears chips efficiently during through-hole drilling. The oxide finish provides a baseline level of lubricity and heat resistance for everyday production use. At 3.875 inches overall length, this bit fits standard drill chucks in benchtop drill presses and handheld drills alike.

This bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and similar ferrous materials. The mechanics length format — shorter overall length than a jobber bit — gives added rigidity in tight-clearance applications such as engine bays, structural members, and equipment enclosures. It is a practical choice for HVAC technicians, pipefitters, electricians, and general maintenance mechanics who need controlled, accurate hole placement in metal without tool deflection.

Key Features

• 135-degree split point self-centers and reduces thrust required to start the cut
• Web-thinned parallel web improves chip evacuation and reduces heat buildup
• High-speed steel construction withstands the heat generated when drilling hard ferrous alloys
• Oxide coating adds surface lubricity for general-purpose metal drilling
• Mechanics length (3.875 inches OAL) provides extra rigidity over standard jobber-length bits
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose replacement or stock mechanics drill bit compatible with standard straight-shank drill chucks on handheld drills, drill presses, and magnetic base drills. Rated for use in carbon steel, cast iron, high alloy steel, high tensile strength alloy, and stainless steel workpieces.

Installation Notes

Install and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the workpiece with a vise or clamps before drilling to prevent rotation injury. Use cutting fluid or oil when drilling stainless steel or high-alloy materials to extend bit life and manage heat. Inspect the cutting edges before each use and replace bits that show chipping, rounding, or discoloration from overheating.
