Import-generic -20925-5 Mechanics Drill Bit 29/64 in Hss

Product Description

The IMPORT-GENERIC -20925-5 is a mechanics-length drill bit designed for general-purpose drilling in metal and alloy applications. Built from high-speed steel with an oxide finish, this bit features a 135-degree split point that self-centers on contact and reduces walking on hard surfaces. The Weldon flat shank provides a positive, slip-resistant grip in compatible chucks. At 4-5/8 inches overall length with a 3-inch flute length, it fits standard drill press and hand drill setups used by machinists, maintenance mechanics, and fabrication technicians.

This drill bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The mechanics length makes it a practical choice for confined-space drilling and close-tolerance work on industrial machinery, structural components, and fabrication fixtures. The right-hand spiral flute efficiently clears chips during through-hole and blind-hole operations. It is sold individually per package with a minimum order quantity of 5 units.

Key Features

• 135-degree split point self-centers and reduces bit walking on metal surfaces
• High-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy steel
• Weldon flat shank with 3 flats prevents rotation and slipping in compatible chucks
• Oxide coating provides corrosion resistance and reduced friction during cutting
• Web-thinned parallel web design lowers cutting resistance and improves chip evacuation
• Mechanics length at 4-5/8 inches overall suits close-clearance drilling applications

Compatibility

Designed for use with drill presses, hand drills, and machining equipment fitted with Weldon-style or flat-shank compatible chucks. Primary workpiece materials include carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance mechanics familiar with rotary cutting tools. Secure the Weldon shank firmly in a compatible chuck before operation and confirm the set screw engages the flat. Always wear appropriate eye protection and secure the workpiece before drilling. Do not run at speeds exceeding the rated RPM for the bit diameter and workpiece material combination.
