Guhring 9055100084000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100084000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 K standards, this bit features a 140-degree split point (SU point type) with web thinning for reduced thrust and cleaner entry. The 8.40 mm (0.3307 inch) diameter is held to a tight tolerance of +0.006 to +0.021 mm, making it suitable for precision hole work. Coolant-through capability supports deep-hole productivity while extending tool life in difficult materials. Shank diameter is 10.00 mm on a straight-cylindrical shank for rigid, positive tool holding in standard drill chucks or collet systems.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machine setups where consistent hole geometry and surface finish are required. Primary workpiece materials are cast iron and steel. The screw machine length body and 3xD flute-to-diameter ratio make it a practical choice for through-hole and blind-hole drilling in production environments. The Series 5510 designation places it in the high-performance submicron carbide grade lineup. A licensed machinist or CNC setup technician is the typical end user for this tool.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree SU split point with web thinning for reduced entry thrust and accurate positioning
• Coolant-through design supports chip evacuation and heat management at depth
• Tight diameter tolerance of +0.006 to +0.021 mm for consistent, repeatable hole size
• DIN 6537 K standard geometry; regular spiral with parallel web configuration
• Straight-cylindrical 10.00 mm shank fits standard collet chucks and drill holders

Compatibility

Designed as an OEM-style replacement or production drill for CNC machining centers and screw machines tooled for a 10.00 mm straight-cylindrical shank. Suitable for drilling cast iron and steel workpieces within the 8.00 to 9.50 mm diameter range category per Series 5510 specifications.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the collet or drill chuck to the specified grip depth to prevent runout. Verify coolant-through passages are clear and that machine coolant pressure is compatible with the tool before beginning a drilling cycle.
