Guhring 9005520015100 Stub Drill Bit 0.0595 in Hss

Product Description

The GUHRING 9005520015100 is a screw machine length (stub) drill bit designed for high-speed steel drilling in tight-clearance applications. Built to DIN 1897 standards, this bit measures 0.0595 inches in diameter (Wire Size 53) with a 130-degree split point and a parabolic flute geometry. The shorter stub length improves rigidity and reduces deflection when drilling small-diameter holes. It features a web-thinned, parallel-web configuration that reduces thrust and improves chip evacuation. The bright, uncoated HSS construction suits general-purpose and high-performance drilling in softer metals and non-ferrous materials. This bit is sold individually with a minimum order quantity of 10 units.

This drill bit is suited for screw machine operations, CNC drilling, and bench drill press work where short, rigid tooling is required. Its primary workpiece material designation is aluminum, making it a practical choice for production shops, machine shops, and maintenance technicians drilling aluminum castings, extrusions, or sheet stock. The right-hand cut and straight-cylindrical shank allow use in standard drill chucks and quick-change toolholders without modification. The 3xD flute-to-diameter ratio and short flute length of approximately 0.4063 inches keep the cutting zone compact and controllable.

Key Features

• DIN 1897 stub length design improves rigidity and reduces bit deflection on small-diameter holes
• 130-degree split point reduces thrust and self-centers on entry
• Parabolic flute profile with web thinning promotes fast chip evacuation
• High-speed steel construction with bright, uncoated finish for use in aluminum and non-ferrous metals
• Straight-cylindrical shank fits standard drill chucks and toolholders
• Diameter tolerance of +0.000 to -0.014 mm for consistent hole sizing

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for use in any standard drill chuck or CNC toolholder accepting a straight-cylindrical shank in the 0.0595-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 0.305 inches per pass without retracting to clear chips.
