Guhring 9006530158700 Drill Bit 0.625 in Hss Tin

Product Description

The GUHRING 9006530158700 is a screw machine length (stub) drill bit designed for high-productivity drilling in metalworking applications. Built from M2 high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life when cutting cast iron and steel. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. At 4.5276 inches overall length with a 2.2835-inch flute length, the stub format provides added rigidity compared to jobber-length bits, making it well suited for production drilling on mills, drill presses, and screw machines. Licensed HVAC techs, machinists, and maintenance professionals rely on this Series 653 geometry for consistent, repeatable hole quality.

This drill bit is engineered for primary use in cast iron and steel workpieces. The straight-cylindrical shank seats securely in standard drill chucks and collets without slippage. The 3xD flute-to-diameter ratio keeps the short flute length in proportion with the 0.625-inch diameter, supporting stable performance in both through-hole and blind-hole drilling. It is a general-purpose grade bit suited to production floor and maintenance shop environments where stub-length rigidity is preferred over extended reach.

Key Features

• M2 high speed steel construction with TiN coating for extended wear resistance
• 118-degree standard drill point angle with web-thinned, tapered web for reduced thrust
• Stub (screw machine) length format provides superior rigidity over jobber-length bits
• Right-hand cut, regular spiral flute with 2-flute configuration for efficient chip removal
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Manufactured to DIN 1897 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement and general-purpose stub drill for use in standard drill chucks and collets accepting a 0.625-inch straight-cylindrical shank, conforming to DIN 1897.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully in a properly rated chuck or collet before operation, and verify spindle speed is appropriate for the workpiece material and bit diameter. Always power down and de-energize the machine before changing tooling. Do not exceed the maximum drilling depth of 2.2835 inches in a single pass without retracting to clear chips.
