The GUHRING 9055250037000 is a solid carbide extra length drill bit designed for precision drilling in demanding machining applications. Built to DIN 6537 standards, this Series 5525 bit features a 3.70 mm (0.1457 inch) diameter, a 140-degree drill point angle, and an internal coolant-through channel that delivers coolant directly to the cutting zone. The FIREX coating provides enhanced wear resistance and heat tolerance. Web thinning and a tapered web configuration reduce entry force and improve chip evacuation. This is a right-hand cutting, spiral-flute tool suited for high-performance production environments operated by machinists and CNC technicians.
This drill bit is engineered for use in cast iron and steel as primary workpiece materials, with secondary capability in aluminum and titanium alloys. The 12xD flute-to-diameter ratio and a maximum drilling depth of 42.00 mm make it well suited for deep-hole drilling cycles in CNC machining centers and drill presses. The straight-cylindrical shank with a 6.00 mm diameter and 36.00 mm shank length seats securely in standard collet chucks and drill chucks. Typical applications include close-tolerance hole production in ferrous and nonferrous components across automotive, aerospace, and general manufacturing industries.
Designed as an OEM-grade replacement or direct-specification drill bit for CNC machining centers and drill presses accepting a 6.00 mm straight-cylindrical shank. Primary workpiece compatibility is cast iron and steel; secondary compatibility includes aluminum and titanium alloys per material codes K, P, H, M, N, and S.
Installation should be performed by a qualified machinist or CNC technician. Secure the shank fully in a compatible collet or drill chuck and verify runout before initiating a drilling cycle. Confirm that the machine coolant system is active before beginning deep-hole operations to prevent tool damage from heat buildup. Follow all applicable machine-guarding and PPE requirements per shop safety standards.
