Guhring 9006510041500 Jobber Drill 4.15mm Hss Tin

Product Description

The GUHRING 9006510041500 is a high speed steel jobber-length drill bit with a titanium nitride (TiN) coating, designed for general-purpose drilling in metalworking applications. The bit measures 4.15 mm in diameter with a 118-degree cone relief point and a two-flute right-hand spiral configuration. Overall length is 75 mm with a 43 mm flute length and a straight-cylindrical shank. The TiN coating increases surface hardness and reduces friction, extending tool life in production and maintenance drilling environments. This is a hand-held or machine-fed tool installed by machinists, tool-and-die workers, and maintenance mechanics.

This drill bit is suited for drilling cast iron and steel workpieces in both shop and field settings. The Series 651 designation follows DIN 338 standards, making it a common specification for CNC drilling machines, drill presses, and hand drills. The 5xD flute-to-diameter ratio and web-thinned point geometry reduce thrust requirements on entry, which is useful when working with tight tolerances or thin-section steel stock. The h8 diameter tolerance on the shank ensures consistent fit in standard collets and chucks.

Key Features

• TiN coating reduces friction and improves wear resistance on cast iron and steel
• 118-degree cone relief point with web thinning for lower entry thrust
• Two-flute right-hand spiral, regular helix for efficient chip evacuation
• Straight-cylindrical shank at 4.15 mm diameter fits standard drill chucks and collets
• DIN 338 Series 651 specification for consistent dimensional accuracy
• h8 shank diameter tolerance for reliable chuck retention

Compatibility

Designed as a general-purpose jobber drill conforming to DIN 338 standards, suitable for use in drill presses, CNC machining centers, and hand drills that accept straight-cylindrical shanks in the 4.00 mm to 5.00 mm range.

Installation Notes

This drill bit is installed by machinists or maintenance technicians in any machine tool or hand drill with a compatible chuck or collet. Secure the shank fully in the chuck before operation and verify runout if used in a precision application. Always wear appropriate eye protection and ensure the workpiece is properly fixtured before drilling. Do not exceed the recommended drilling depth of 36.78 mm for this bit length.
