Guhring 9005150016100 Drill Bit Size 52 130 Deg Stub

Product Description

The GUHRING 9005150016100 is a stub-length (screw machine length) twist drill bit designed for high-productivity drilling in steel and cast iron. Built from powdered metal and finished with a multi-layer nano-FIREX coating, it delivers extended tool life in demanding production environments. The bit features a 130-degree cone relief point with web thinning for reduced thrust and cleaner entry, and a parabolic flute geometry that promotes fast chip evacuation. Overall length is 1.3386 inches (34.00 mm), with a 0.0635-inch decimal diameter and an h8 shank diameter tolerance for consistent chuck fit. Licensed HVAC techs, machinists, and tool-room professionals reach for this bit when cycle time and hole quality matter.

This drill bit is sized at wire gauge 52 (0.0635 inches) and is suited for precision drilling operations in ferrous materials including steel and cast iron. Its stub-length body reduces deflection in short-reach applications such as CNC machining centers, turret lathes, and screw machines. The straight cylindrical shank accepts standard drill chucks and collets. The parabolic fast-spiral flute design clears chips efficiently at higher feed rates, making it a practical choice for production runs where consistent hole geometry and tight tolerances are required. Conforms to DIN 1897 specification.

Key Features

• Multi-layer nano-FIREX coating for extended wear resistance in ferrous materials
• 130-degree cone relief point with web thinning reduces entry thrust and improves centering
• Parabolic fast-spiral flutes for aggressive chip evacuation at higher feed rates
• Stub length (1.3386 inches OAL) minimizes deflection in short-reach setups
• h8 shank diameter tolerance ensures repeatable fit in precision chucks and collets
• Conforms to DIN 1897 standard; no coolant-through required

Compatibility

Designed for drilling steel and cast iron workpieces. Straight cylindrical shank is compatible with standard drill chucks and collets sized for a 0.0634-inch (1.61 mm) shank diameter. Conforms to DIN 1897 Series 515 geometry.

Installation Notes

Installation and use should be performed by qualified machinists or tool-room technicians familiar with rotating cutting tools and machine safety procedures. Secure the shank fully in a calibrated chuck or collet and confirm runout before beginning a cut. Power down and lock out the machine spindle before changing or inspecting the bit. Do not exceed the recommended maximum drilling depth of 0.2990 inches (7.59 mm) per pass for this stub-length geometry.
