Guhring 9003360038000 Taper Length Drill Bit 0.1495 in

Product Description

The GUHRING 9003360038000 is a taper length drill bit engineered for demanding metal-cutting applications. Built from cobalt high-speed steel, it delivers heat resistance and edge retention when drilling cast iron, hardened materials, stainless steel, and carbon steel. The 130-degree split point reduces walking and lowers thrust force at entry. With a parabolic flute geometry and web-thinned tip, chip evacuation stays efficient through the full depth of cut. Overall length is 4.6875 inches with a 3.0625-inch flute length, giving it the reach needed for deeper holes that standard jobber-length bits cannot access. Shank diameter is 0.1496 inches, cylindrical, for use in standard drill chucks and collet holders.

This bit is sized to Wire Gauge 25 (0.1495 inches decimal) and is suited for precision hole work in ferrous metals encountered in machining, fabrication, and maintenance-repair operations. The Series 336 designation follows DIN 340 standards, making it a recognized format for production shops and toolrooms. Right-hand cut, no coolant-through, and a parallel web configuration keep the design straightforward for general-purpose taper-length drilling on vertical mills, drill presses, and CNC machining centers where extended reach is required.

Key Features

• Cobalt tool material for elevated heat resistance in stainless steel and hardened material applications
• 130-degree point angle with web-thinned tip reduces entry thrust and improves self-centering
• Parabolic flute geometry promotes efficient chip clearing at depths up to 2.846 inches
• Taper length body at 4.6875 inches overall provides extended reach versus standard jobber-length drills
• DIN 340 specification ensures dimensional consistency for toolroom and production use
• Bright uncoated finish allows easy visual inspection of edge condition after regrinding

Compatibility

Designed as a DIN 340 taper length drill bit with a 0.1496-inch cylindrical shank, compatible with standard drill chucks, Jacobs-taper arbors, and collet systems sized for the corresponding shank diameter. Rated for cast iron, hardened materials, stainless steel, and steel per manufacturer material application data.

Installation Notes

Installation and use should be performed by machinists or qualified trade professionals familiar with rotating cutting tool safety. Secure the cylindrical shank firmly in a properly sized chuck or collet before operating; verify runout is within acceptable limits before drilling. Always follow applicable machine guarding requirements and wear appropriate eye protection. Do not exceed the drill press or machining center rated speed for the workpiece material and bit diameter.
