Guhring 9005150035700 Screw Machine Drill Bit 0.1405 in

Product Description

The GUHRING 9005150035700 is a screw machine length (stub) drill bit designed for high-productivity metal drilling in tight-clearance and production environments. Built from powdered metal (PMASP60 grade) with a coated finish, this bit delivers consistent performance on cast iron and steel. The 130-degree drill point angle and web-thinned, parallel web construction reduce thrust and improve chip evacuation at entry. At 0.1405 inches in diameter with a 2.0472-inch overall length, it fits standard straight-cylindrical chuck collets and screw machine setups. A parabolic flute geometry aids chip flow in short-hole applications.

This drill bit is intended for stub-length drilling operations in ferrous materials including cast iron and steel. The abbreviated flute length of 0.7874 inches and a maximum drilling depth of 0.577 inches make it well suited for production screw machine work, CNC drilling centers, and drill press applications where rigid setups and repeatable shallow-to-medium depth holes are required. It is sized as wire gauge #28 and follows DIN 1897 geometry standards, making it a direct fit for metric-spec tooling programs common in precision manufacturing and trade machining shops.

Key Features

• Powdered metal (PMASP60) construction with coated finish for extended tool life in ferrous materials
• 130-degree drill point angle reduces thrust and improves centering on entry
• Parabolic flute geometry promotes efficient chip evacuation in stub-depth holes
• Web-thinned parallel web lowers cutting resistance and extends drill life
• Straight-cylindrical shank fits standard drill chucks and collet systems without modification
• Conforms to DIN 1897 specification for consistent geometry and interchangeability

Compatibility

Designed as a DIN 1897-compliant stub drill bit for use in cast iron and steel applications. Compatible with any standard straight-cylindrical chuck or collet system accepting a 0.1405-inch shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Power down the machine completely before changing tooling. Do not exceed the maximum drilling depth of 0.577 inches for this stub-length geometry, as extended-depth passes beyond the rated flute length can cause chip packing and bit failure.
