Guhring 9055140090000 Screw Machine Drill Bit 0.3543 in

Product Description

The GUHRING 9055140090000 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. It measures 0.3543 inches in diameter with a 140-degree split point and a web-thinned, parallel web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 10.00 mm and fits standard drill chucks. At 89.00 mm overall length with a 47.00 mm flute length, this stub-length geometry delivers rigidity in tight setups. Machinists, tool-and-die professionals, and production drilling operations rely on this series for consistent performance in ferrous materials.

This bit is suited for production machining environments where cast iron and steel are the primary workpiece materials. The screw machine length keeps deflection low in short-reach applications such as CNC machining centers, turret lathes, and drill presses. The 3xD flute-to-diameter ratio supports controlled chip flow at typical production feeds and speeds. No coolant-through capability is present, so external coolant or cutting fluid application is standard practice for this configuration.

Key Features

• Solid carbide submicron-grade construction for hardness and wear resistance in ferrous materials
• 140-degree SU split point reduces walking and decreases required thrust force
• Web-thinned parallel web improves chip clearance and cutting efficiency
• Regular spiral flute with right-hand cut for standard production drilling
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Conforms to DIN 6537 K specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use carbide drill bit for production machining applications involving cast iron and steel workpieces, conforming to DIN 6537 K standards for screw machine length carbide drills.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Secure the straight-cylindrical shank fully in a properly sized chuck or collet before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before initiating the cut. Inspect the cutting edges and point for chips or wear before each use, as carbide tooling can fracture if run with damaged geometry.
