Guhring 9057410063500 Screw Machine Drill Bit

Product Description

The GUHRING 9057410063500 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537 K standards, this bit features a 140-degree split point (SU type) with web thinning to reduce entry thrust and improve centering on hard workpieces. The 2-flute spiral configuration in a regular helix promotes efficient chip evacuation. At 0.25 inches (decimal 0.2500) in diameter, the bit is sized to letter designation E. The straight-cylindrical shank measures 8.00 millimeters in diameter. Solid carbide construction with a coated finish provides the wear resistance required when cutting titanium alloys and similarly abrasive materials. Installation is handled by machinists and tool-and-die professionals working in CNC and manual machine environments.

This drill bit is designated for primary use in titanium alloy workpieces, where tool rigidity and cutting geometry are critical to hole quality and tool life. The screw machine length profile keeps the drill short and stiff, reducing deflection during deep-pass operations. The maximum drilling depth reaches 0.9640 inches (24.48 mm), placing it in a 3xD flute-to-diameter ratio category. The coated finish reduces friction and heat buildup at the cutting zone. This bit is part of the GUHRING Series 5741, a line built to high-performance grade specifications for production machining environments.

Key Features

• Solid carbide construction rated to K40 material grade for extended tool life in hard materials
• 140-degree SU split point with web thinning reduces thrust and improves self-centering
• 2-flute regular spiral design promotes chip clearance in blind and through-hole applications
• Screw machine length body minimizes deflection and improves rigidity in short-reach setups
• Coated finish reduces friction and thermal wear at the cutting edge
• Conforms to DIN 6537 K standard for consistent geometry and dimensional tolerance (m7)

Compatibility

Designed as an OEM-style replacement or direct-use bit for CNC machining centers and manual drill presses requiring a 0.25-inch straight-shank screw machine length carbide drill, particularly in titanium alloy and similarly hard workpiece applications within the GUHRING Series 5741 product family.

Installation Notes

Installation is performed by machinists or toolroom technicians in a machine shop environment. Power down and de-energize the spindle before changing tooling, and verify chuck or collet torque specifications against the machine manufacturer guidelines. Confirm shank diameter compatibility with the collet or chuck before seating the bit. Do not exceed the rated maximum drilling depth of 0.9640 inches per pass without accounting for chip evacuation requirements.
