Guhring 9055140155000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140155000 is a solid submicron carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. With a 0.6102-inch diameter, a 140-degree split point angle, and web-thinned geometry, this bit delivers precise entry and reduced thrust in hard workpiece materials. The coated finish extends tool life under continuous cutting loads. Two spiral flutes with a regular helix provide consistent chip evacuation. This bit is sized and built for use by machinists and toolroom technicians running CNC or manual equipment in metal fabrication and production shops.

This drill bit is suited for drilling cast iron and steel in screw machine and short-hole applications where rigidity and dimensional accuracy are critical. The screw machine length body keeps deflection low, making it appropriate for tight-tolerance bores in production runs. The straight-cylindrical shank with a 16.00 mm diameter seats securely in standard drill chucks and collet holders. Maximum drilling depth reaches 1.644 inches, supporting a 3xD depth-to-diameter ratio. It conforms to DIN 6537 K standards, consistent with tooling used in precision metal-cutting operations.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance in ferrous materials
• 140-degree SU split point angle reduces walking and lowers entry thrust
• Web-thinned, parallel web configuration improves chip flow and cutting efficiency
• Coated finish extends tool life in cast iron and steel applications
• Screw machine length body minimizes deflection for tight-tolerance drilling
• Conforms to DIN 6537 K specification for consistent dimensional standards

Compatibility

Designed for use in cast iron and steel workpieces, this bit is compatible with standard drill chucks and collet tool holders accepting a 16.00 mm straight-cylindrical shank, per Series 5514 tooling standards.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank fully in a properly sized chuck or collet holder before operation, and verify runout before drilling production parts. Power down and de-energize the machine spindle completely before changing tooling. Do not exceed the maximum drilling depth of 1.644 inches without repositioning or retracting to clear chips.
