Import 20811 Mechanics Drill Bit 0.191 in Hss Split Point

Product Description

The IMPORT 20811 is a mechanics-length high-speed steel drill bit designed for general-purpose drilling in metalworking applications. With a 0.191-inch diameter and a 135-degree split point, it starts on contact without a center punch and reduces walking on hard surfaces. The split point geometry also lowers thrust force, making it well suited for hand-held drills and drill presses alike. The oxide coating provides mild corrosion resistance and helps retain cutting fluid at the flute surface. At 3.5 inches overall length with a 2-inch flute, this bit fits standard chucks and keeps a low profile in tight clearance spots. Licensed HVAC, plumbing, and electrical trades routinely carry mechanics-length bits for sheet metal, pipe flange, and enclosure work.

This bit is intended for right-hand cutting in a broad 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 keeps the bit rigid in applications where a jobber-length bit would flex or chatter. Spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole drilling at typical shop and field feed rates. It is sold individually but requires a minimum order of 3 units.

Key Features

• 135-degree split point starts on contact and reduces walking without a center punch
• High-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy steel
• Mechanics length at 3.5 inches overall keeps the bit rigid in tight clearance applications
• Oxide finish provides mild corrosion resistance and aids lubrication retention
• Web-thinned parallel web lowers cutting thrust and extends bit life
• Straight-cylindrical shank fits standard 3-jaw and keyless chucks without adapters

Compatibility

Designed as a general-purpose mechanics-length drill bit suitable for use in standard drill presses, magnetic-base drills, and hand-held corded or cordless drills with a straight-cylindrical chuck.

Installation Notes

Installation is performed by machinists, metal fabricators, and licensed trade technicians working with ferrous metal assemblies. Secure the workpiece before drilling and use cutting fluid or coolant appropriate for the base material to extend bit life. This bit does not support coolant-through delivery. Inspect the cutting edge before each use and replace the bit if the point shows chipping or heat discoloration.
