Guhring 9005520054000 Screw Machine Drill Bit 5.40mm Hss

Product Description

The GUHRING 9005520054000 is a screw machine length drill bit designed for high-productivity metal drilling applications. Built from M2 high-speed steel with a bright, uncoated finish, this bit features a 130-degree cone relief point and a parabolic flute geometry that promotes efficient chip evacuation and reduced thrust in short-hole drilling. At 5.40 mm in diameter with a 2.5984-inch overall length, it fits the stub-length format preferred in production and CNC machining environments where clearance is limited and rigidity is critical. The web-thinned design lowers cutting resistance at entry, making it well suited for high-cycle drilling in ferrous and non-ferrous materials.

This drill bit is intended for use in machine shop, production floor, and maintenance environments. The straight-cylindrical shank seats directly in standard drill chucks, collets, and quick-change tooling systems. The 3xD flute-to-diameter ratio and parabolic flute form support consistent chip flow in materials such as mild steel, alloy steel, aluminum, and similar workpiece materials. It is appropriate for use in drill presses, CNC machining centers, lathes, and hand-held power tools where a stub-length bit provides better control and reduced deflection compared to jobber-length alternatives.

Key Features

• 5.40 mm diameter with h8 tolerance for consistent, repeatable hole sizing
• 130-degree cone relief point with web thinning for reduced entry thrust
• Parabolic flute geometry promotes rapid chip evacuation from the cut zone
• M2 high-speed steel construction rated for heavy-duty drilling grade applications
• Straight-cylindrical shank compatible with standard chucks and collet systems
• DIN specification designation, Series 552, for cross-reference and replacement sourcing

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for applications requiring a stub-length, straight-shank drill bit in the 5.00 mm to 6.50 mm diameter range per DIN Series 552 specification.

Installation Notes

Installation is performed by machinists and tool-and-die professionals in machine shop or production environments. Power down and de-energize the spindle before seating or removing the bit from the chuck or collet. Verify shank diameter and chuck capacity match before tightening. Do not exceed the recommended speed and feed parameters for the workpiece material and machine type.
