Guhring 9055140041000 Carbide Drill Bit 0.1614 in

Product Description

The GUHRING 9055140041000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. It measures 0.1614 inches in diameter with a 140-degree split point and a web-thinned, parallel web geometry that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 6.00 millimeters in diameter, and the overall length is 66.00 millimeters. Two spiral flutes handle chip removal in right-hand cutting applications. This bit is manufactured to DIN 6537K standards using submicron carbide grade material, making it suitable for precision drilling in production and maintenance environments where dimensional consistency is required.

This drill bit is suited for drilling cast iron and steel in screw machine, CNC, and production drilling setups. The 3xD flute-to-diameter ratio and SU point type make it appropriate for short-hole drilling cycles where repeatability and hole quality are critical. It is commonly used by machinists and tool-and-die professionals in shop environments running high-cycle operations. The maximum drilling depth is 0.7030 inches (17.85 millimeters), consistent with its screw machine length classification.

Key Features

• Solid submicron carbide construction for wear resistance in steel and cast iron
• 140-degree SU point with web thinning reduces entry thrust and improves centering
• Two spiral flutes with regular helix for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Manufactured to DIN 6537K specification for consistent dimensional tolerancing
• Diameter tolerance of +0.004 to +0.016 mm for close-tolerance hole applications

Compatibility

Designed for use in standard drill chucks and collets accepting a 6.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel. Falls within the 0.1500 to 0.2000 inch drill bit size range of the GUHRING Series 5514 product family.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in a collet or drill chuck before operation and verify runout before beginning a drilling cycle. Ensure the workpiece is properly fixtured and that spindle speed and feed rate are set according to the workpiece material and machine specifications. This bit does not support coolant-through delivery, so external coolant or cutting fluid application is recommended when drilling steel at sustained cycle rates.
