Guhring 9055100135000 Screw Machine Drill Bit 13.50mm

Product Description

The GUHRING 9055100135000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in cast iron and steel. It measures 13.50 mm in diameter with a 140-degree split point and an overall length of 107 mm (4.2126 inches). The straight-cylindrical shank measures 14.00 mm in diameter and 47.00 mm in length. Built to DIN 6537 K standards from submicron carbide grade material, this bit delivers the rigidity and edge retention required for production drilling environments where tool life and hole quality are critical. Coolant-through capability supports chip evacuation and thermal management at higher feed rates.

This drill bit is suited for metalworking applications involving cast iron and steel workpieces in both job shop and production settings. The screw machine length format provides a compact, rigid profile that reduces deflection in short-reach drilling operations. The 2-flute spiral design with web thinning and parallel web configuration supports efficient chip flow. With a flute-to-diameter ratio of 3xD and a maximum drilling depth of 57.00 mm, this bit is appropriate for through-hole and blind-hole work where dimensional accuracy and tool stability are required. Licensed machinists and precision metalworking technicians are the primary installers.

Key Features

• Solid carbide construction in submicron material grade for extended wear resistance in ferrous materials
• 140-degree SU point geometry with web thinning reduces entry force and improves centering accuracy
• Coolant-through design supports internal coolant delivery for chip evacuation and heat control
• Straight-cylindrical shank at 14.00 mm diameter for secure chuck or collet retention
• Manufactured to DIN 6537 K specification for dimensional consistency and interchangeability
• Diameter tolerance of +0.007 to +0.025 mm ensures tight hole tolerances in precision applications

Compatibility

Designed for use in CNC machining centers, drill presses, and manual machines equipped with a collet or drill chuck accepting a 14.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel. Series 5510, DIN 6537 K.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or drill chuck before operation. Confirm coolant-through passages are clear and coolant pressure is set per shop standards before engaging the workpiece. Do not exceed the maximum drilling depth of 57.00 mm in a single pass without retracting to clear chips.
