Guhring 9055150037000 Carbide Jobber Drill Bit 3.7mm

Product Description

The GUHRING 9055150037000 is a solid carbide jobber-length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537L standards, it features a 140-degree split-point (SU) tip geometry that promotes self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance, extending tool life in demanding production environments. At 66 mm overall length with a 28 mm flute length and a 5xD flute-to-diameter ratio, this bit delivers consistent chip evacuation in moderate-depth holes. The tapered web with web thinning reduces thrust and improves cutting efficiency. This is a professional-grade tool suited for machinists, toolroom technicians, and maintenance trades working with ferrous materials.

The 9055150037000 is intended for drilling cast iron and steel workpieces in production machining, toolroom, and industrial maintenance applications. The straight-cylindrical shank at 6 mm diameter seats securely in standard drill chucks and collet holders. With a maximum drilling depth of 22.45 mm and a submicron carbide grade, it performs reliably in CNC machining centers and floor-model drill presses alike. The regular spiral flute geometry handles chip clearance in both through-hole and blind-hole drilling scenarios within the 5xD depth range.

Key Features

• Solid carbide construction, submicron grade for hardness and edge retention in ferrous materials
• FIREX coating for elevated thermal resistance and extended tool life
• 140-degree SU split-point tip for self-centering entry without a pilot hole
• Web-thinned tapered web reduces axial thrust and cutting force
• Straight-cylindrical 6 mm shank compatible with standard chucks and collet systems
• Conforms to DIN 6535 and DIN 6537L dimensional standards

Compatibility

Designed as an OEM-style replacement or direct substitute for jobber-length carbide drill bits conforming to DIN 6537L in the 3.00 mm to 4.00 mm diameter range. Primary workpiece material compatibility per manufacturer data includes cast iron (material code K) and steel (material code P).

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating depth and chuck runout before commencing a cut, as carbide tooling is sensitive to lateral loading from misalignment. Do not use this bit in hand-held portable drills; it is intended for rigid-setup machine tool applications.
