Import 20830 Mechanics Drill Bit 0.1285 in Hss Split Point

Product Description

The IMPORT 20830 is a mechanics-length drill bit designed for general-purpose drilling in metal and ferrous materials. Built from high-speed steel with an oxide finish, it features a 135-degree split point that reduces walking on contact and requires less feed pressure than a standard 118-degree point. The straight-cylindrical shank is compatible with standard drill chucks. At 0.1285 inches in diameter and 2-3/4 inches overall length, this bit is suited for close-quarter or depth-restricted drilling applications common in fabrication, maintenance, and repair work.

This drill bit is intended for use in production and maintenance drilling where a mechanics-length tool is required for access or rigidity. It is rated for use in carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The spiral flute geometry promotes chip evacuation during through-hole drilling. Right-hand cut configuration is standard for use with conventional drill presses, hand drills, and mill spindles.

Key Features

• 135-degree split point reduces bit walking and lowers required feed force
• High-speed steel construction provides heat resistance for metal drilling
• Oxide coating improves lubricity and corrosion resistance during storage and use
• Mechanics-length body offers greater rigidity than jobber-length bits in tight spaces
• Web-thinned construction reduces cutting resistance at the center of the bit
• Straight-cylindrical shank fits standard 3-jaw drill chucks without modification

Compatibility

Designed as a general-purpose replacement mechanics drill bit for use in standard drill chucks accepting straight-cylindrical shanks, compatible with carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and steel workpieces.

Installation Notes

Installed by machinists, maintenance technicians, and fabricators using standard drill presses, hand drills, or milling machines. Secure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the spindle. Use appropriate cutting fluid when drilling stainless or high-alloy steels to extend tool life. Do not exceed the recommended feed rate for the workpiece material or bit diameter.
