Guhring 9006530025300 Screw Machine Drill Bit 0.0995in Hss

Product Description

The GUHRING 9006530025300 is a stub-length screw machine drill bit designed for high-volume, precision drilling in metal fabrication and machining applications. Built from M2 high speed steel with a coated finish, this bit measures 0.0995 inches (wire size 39) in diameter and delivers a 118-degree cone relief point angle with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. It is a heavy-duty grade tool suited for production environments where consistent hole quality and tool life are critical priorities.

This bit is engineered for drilling cast iron and steel in screw machine, CNC, and manual drill press setups. The stub flute length — 14.00 millimeters — provides added rigidity compared to jobber-length bits, making it well-suited for shallow holes where deflection control matters. The 2-flute regular spiral configuration and web-thinned point reduce chip packing in tight-depth applications. Maximum recommended drilling depth is 0.402 inches (10.21 mm), consistent with its 3xD flute-to-diameter ratio. This product ships individually (package quantity of 1) and must be ordered in multiples of 10.

Key Features

• M2 high speed steel construction with coated finish for extended tool life in ferrous materials
• 118-degree cone relief point with web thinning for reduced entry thrust
• Stub flute length (14.00 mm) provides increased rigidity and deflection resistance
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 1897 standard, Series 653, with h8 diameter tolerance for consistent sizing
• Right-hand cut, 2-flute regular spiral — optimized for cast iron and steel

Compatibility

Designed as an OEM-style replacement or production consumable for screw machine, CNC drill, and manual drill press operations requiring a wire-gauge size 39 (0.0995 inch) stub-length drill bit in ferrous materials.

Installation Notes

This drill bit is installed and serviced by machinists and tool-and-die professionals using standard drill chucks, collet systems, or quick-change toolholders. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet bore is clean and within tolerance before seating the straight shank. Do not exceed the recommended maximum drilling depth of 0.402 inches per the 3xD flute ratio, and use appropriate cutting fluid for steel applications to maintain tool life.
