Guhring 9005520043000 Stub Drill Bit 0.1695 in Hss

Product Description

The GUHRING 9005520043000 is a screw machine length (stub) drill bit designed for fast, accurate drilling in production and maintenance environments. Built from high speed steel with a bright/uncoated finish, it measures 0.1695 inches in diameter and carries a wire gauge designation of No. 18. The 130-degree split point with web thinning reduces entry force and walking on startup. The parabolic flute geometry promotes efficient chip evacuation, which is critical when drilling deep relative to diameter. Machinists, tool-and-die technicians, and production floor operators working with CNC machines, drill presses, and screw machines reach for this bit when cycle times and hole quality both matter.

The 9005520043000 is built to DIN 1897 specification, placing it in the stub-length class preferred in screw machine and turret lathe applications where rigidity and minimal deflection are priorities. The straight cylindrical shank fits standard drill chucks without an adapter. Primary workpiece material is aluminum, though the HSS construction also handles plastics and other non-ferrous materials in the same diameter range. The Series 552 family covers decimal inch sizes from 0.1500 to 0.2000 inches, making this bit part of a matched progression for shops drilling graduated hole sizes.

Key Features

• DIN 1897 stub-length standard for maximum rigidity and minimal runout in short-reach applications
• 130-degree point angle with web thinning for self-centering entry and reduced thrust force
• Parabolic flute design with 3xD flute-to-diameter ratio for efficient chip clearing in aluminum and non-ferrous materials
• Bright/uncoated HSS finish maintains sharpness through regrinding cycles
• Straight cylindrical shank fits standard drill chucks and collets without adapters
• Parallel web configuration maintains consistent cutting geometry across the full flute length

Compatibility

Designed as an OEM-style production drill bit compatible with standard straight-shank drill chucks and collets on CNC machining centers, drill presses, turret lathes, and automatic screw machines accepting bits in the No. 18 wire gauge diameter class.

Installation Notes

Installation is performed by machinists and toolroom technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Confirm chuck or collet bore is clean and free of debris before seating the straight shank to prevent runout. When drilling aluminum or non-ferrous materials, use an appropriate cutting fluid to extend tool life and maintain surface finish quality.
