Guhring 9055190022600 Cobalt Drill Bit Wire 43

Product Description

The GUHRING 9055190022600 is a cobalt jobber length drill bit designed for precision drilling in demanding shop and field environments. Built to DIN 338 standards, it carries an M35 cobalt material grade and a titanium nitride (TiN) coating that extends tool life when cutting through abrasive or work-hardening materials. The drill measures 0.0890 inches in diameter (Wire Size 43) with an overall length of 53.00 mm (approximately 2.09 inches) and a flute length of 27.00 mm. The four-facet split point geometry reduces walking on entry and lowers thrust requirements. Installation is handled by machinists, tool-and-die technicians, and trade professionals running drill presses, CNC machines, or hand-held power tools.

This bit is sized for small-diameter work, making it well suited for aluminum, steel, and other materials falling within the K, M, N, and P workpiece material codes under DIN 338 classification. Typical applications include tapping pre-drill operations, sheet metal work, and precision hole-making in light-gauge stock. The straight-cylindrical shank seats in standard drill chucks without adapters. A maximum drilling depth of 23.61 mm (0.93 inches) is supported at this diameter and flute configuration. The bit ships individually and carries a minimum order quantity of 10 units, making it practical for stocking in tool cribs or service vans.

Key Features

• M35 cobalt construction handles elevated cutting temperatures better than standard HSS bits
• Titanium nitride (TiN) coating reduces friction and improves wear resistance
• Four-facet split point with web thinning minimizes drill walk and reduces thrust
• Right-hand spiral flute with regular helix clears chips efficiently in through-hole applications
• DIN 338 standard geometry ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard 3-jaw drill chucks without modification

Compatibility

Designed as a DIN 338-compliant jobber length drill bit suitable for use in standard drill chucks accepting a 2.26 mm straight shank across drill presses, hand drills, and CNC drilling operations.

Installation Notes

Secure the shank fully in the chuck and verify runout before beginning a drilling cycle. Power down or de-energize the machine and engage any spindle lock before changing bits. Apply cutting fluid appropriate to the workpiece material to maximize coating life and dimensional accuracy. Inspect the cutting edges for chipping or TiN coating wear after extended use in hard or abrasive materials.
