Import 27528 No. 28 Hss Jobber Drill Bit 118 Degree

Product Description

The IMPORT 27528 is a No. 28 wire gauge jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It is made from high speed steel with an oxide coating that provides lubricity and basic corrosion resistance. The bit features a standard 118-degree split point angle for reliable starting and a spiral flute with a regular helix for efficient chip evacuation. Overall length is 2-7/8 inches with a flute length of 1-3/4 inches. The decimal inch size is 0.1405 inches. This bit is installed and used by machinists, maintenance technicians, HVAC and plumbing trades, and general contractors working with light-gauge materials.

The 27528 is suited for benchtop drill presses, hand drills, and drill-tap operations in light industrial and mechanical maintenance settings. It falls within the 0.1000 to 0.1500 decimal inch size range and is appropriate for residential and commercial maintenance, fabrication shops, and field service work where a small-diameter general-purpose bit is needed. The straight-cylindrical shank fits standard drill chucks without modification.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using standard keyed or keyless drill chucks. Secure the shank fully in the chuck before operation and confirm the bit runs true before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life. Follow standard shop safety practices including eye protection and secure workpiece clamping.
