Import 20900 Mechanics Drill Bit 1/16 Inch Hss Split Point

Product Description

The IMPORT 20900 is a mechanics-length high-speed steel drill bit designed for general-purpose drilling in metal and ferrous materials. The 1/16 inch diameter bit features a 135-degree split point that reduces walking on contact, allowing the bit to begin cutting without a center punch in many applications. The oxide coating provides moderate surface hardness and corrosion resistance. At 1-7/8 inches overall length, this is a short, rigid geometry suited to close-quarter drilling where a jobber-length bit would flex or chatter. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations.

This bit is intended for use in drill presses, hand drills, and right-angle drill attachments where tight clearance demands a compact tool. It is appropriate for production and maintenance work on carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The short flute length of 7/8 inch and parallel web configuration make it well-suited to machinists, maintenance technicians, and fabricators who need a stiff bit in confined spaces.

Key Features

• 135-degree split point reduces drill walking and lowers required feed pressure at entry
• High-speed steel construction withstands heat generated during ferrous metal drilling
• Oxide finish adds surface hardness and basic corrosion resistance
• Mechanics length (1-7/8 inches OAL) provides rigidity in tight clearance applications
• Web-thinned parallel web reduces cutting resistance and improves chip flow
• Right-hand cut with regular spiral flutes for standard drill and press use

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with standard straight-shank drill chucks on hand drills, drill presses, and right-angle attachments accepting 1/16 inch straight-cylindrical shanks.

Installation Notes

Secure the shank fully in the chuck before operation and verify there is no runout before drilling. When drilling stainless steel or high-alloy materials, use appropriate cutting fluid and moderate feed pressure to avoid work-hardening the surface. Always wear eye protection and ensure the workpiece is clamped or fixtured before contact. Replace the bit if point geometry shows signs of dulling, as forcing a worn split-point bit increases heat and can cause breakage at this diameter.
