Guhring 9003360039100 Taper Length Drill Bit 0.1540in

Product Description

The GUHRING 9003360039100 is a taper length cobalt drill bit designed for demanding metal cutting applications in production and maintenance environments. Sized at 0.1540 inches in diameter (Wire Size 23), this bit features a 130-degree point angle and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup. The cylindrical shank and web-thinned, parallel web construction improve centering accuracy and lower thrust requirements at the spindle. Licensed machinists, tool-and-die technicians, and fabrication shops use this bit where standard jobber-length drills lack the reach or performance required for tougher workpiece materials.

This drill bit is rated for use in cast iron, hardened materials, stainless steel, and steel. Its 10xD flute-length-to-diameter ratio gives it the reach needed for deeper-than-standard hole depths without excessive tool deflection. The taper length body makes it suitable for setups requiring extended reach in production drilling fixtures, CNC machining centers, and manual drill presses where a jobber-length drill will not reach the required depth. Right-hand cut geometry is standard for conventional spindle rotation.

Key Features

• Cobalt high-performance tool material for heat and wear resistance in ferrous and hardened materials
• 130-degree standard point angle with web-thinned, parallel web for improved centering and reduced thrust
• Parabolic flute design promotes fast chip evacuation and reduces packing in deep holes
• 10xD flute-length-to-diameter ratio provides extended reach for taper-length applications
• Bright/uncoated finish — no coating buildup to affect hole tolerances
• Manufactured to DIN 340 specification for consistent dimensional control

Compatibility

Designed as a taper length replacement drill bit for Series 336 applications in cast iron, hardened materials, stainless steel, and steel workpieces requiring a 0.1540-inch diameter hole per DIN 340 standards.

Installation Notes

Installation of this drill bit is performed by machinists and tooling technicians in shop environments. Secure the cylindrical shank fully in a compatible drill chuck or collet before operation and verify runout is within acceptable limits for the tolerance class required. Power down and de-energize the machine spindle completely before changing tooling. Do not exceed the rated maximum drilling depth of 2.84 inches without confirming chip clearance and coolant strategy for the specific material being drilled.
