Guhring 9003360040000 Taper Length Drill Bit 0.1575in

Product Description

The GUHRING 9003360040000 is a cobalt taper length drill bit designed for demanding metal-cutting applications in production and maintenance environments. Built to DIN 340 standards, it features a 130-degree split point, a parabolic flute geometry, and a web-thinned tip that reduces thrust and improves chip evacuation. The 0.1575-inch diameter pairs with a cylindrical shank of equal diameter for straightforward chuck mounting. With a flute-to-diameter ratio of 10xD, the bit reaches deeper than jobber-length tooling while maintaining rigidity. Machinists and toolroom technicians are the primary users, typically in CNC drilling centers, drill presses, and manual machine tools where consistent hole quality in tough materials is required.

This bit is suited for drilling cast iron, hardened materials, stainless steel, and carbon steel. The parabolic flute design accelerates chip removal when working through stainless and other gummy alloys, reducing heat buildup and extending tool life. The right-hand cut and cylindrical shank make it compatible with standard drill chucks and collet systems. It is appropriate for both light production runs and repetitive drilling cycles in job shop and manufacturing settings.

Key Features

• Cobalt construction for heat resistance and durability in hard and abrasive materials
• 130-degree point angle reduces entry thrust and improves self-centering on flat surfaces
• Parabolic flute geometry promotes fast, clean chip evacuation in deep-hole drilling
• Web-thinned tip with parallel web configuration minimizes walking and reduces required feed force
• 10xD flute-to-diameter ratio enables deeper penetration than standard jobber-length bits
• Bright/uncoated finish maintains close diameter tolerance per DIN 340 specification

Compatibility

Designed as a DIN 340 taper length drill bit for use in standard drill chucks and collet holders accepting a 0.1575-inch cylindrical shank. Suitable for cast iron, hardened materials, stainless steel, and steel workpieces.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with drill press or CNC machine operation. Secure the shank fully in the chuck or collet and verify runout before cycling. Power down and de-energize the machine before changing tooling. Do not exceed the maximum drilling depth of 2.835 inches without retracting to clear chips, particularly when drilling stainless or cast iron.
