Kennametal 4150685 Carbide Jobber Drill 6.10 Mm Tin

Product Description

The KENNAMETAL 4150685 is a solid carbide jobber-length drill bit designed for precision hole-making in metalworking and machining applications. The bit measures 6.10 mm (0.2402 inches) in diameter with an overall length of 91.00 mm (3.5827 inches) and a flute length of 53.00 mm (2.0866 inches). A 140-degree split-point geometry reduces walking and improves chip evacuation at entry. The titanium nitride (TiN) coating extends wear resistance and reduces friction on the cutting edges. This drill is suited for use in CNC machining centers, drill presses, and manual lathes where consistent bore diameter and surface finish are required. Installation and operation are handled by machinists, tool-and-die makers, and CNC operators.

This jobber drill is sized for general-purpose drilling in ferrous and non-ferrous metals, plastics, and composite materials. The 7xD flute-to-diameter ratio and two-flute spiral geometry support efficient chip clearing in moderate-depth bores up to 43.00 mm. The straight cylindrical shank at 8 mm diameter fits standard drill chucks and collet systems without adapters. Right-hand cutting direction is the conventional configuration for standard drill press and CNC spindle setups.

Key Features

• Solid carbide construction for high rigidity and thermal resistance versus high-speed steel alternatives
• TiN coating reduces cutting friction and extends tool life in production runs
• 140-degree point angle improves self-centering and reduces thrust force on entry
• Two-flute regular spiral geometry promotes continuous chip evacuation
• Straight cylindrical shank compatible with standard chucks and collet holders
• Right-hand cut in conventional spindle direction — no special tooling required

Compatibility

Designed for use in standard drill chucks and collet systems accepting an 8 mm straight shank, across CNC machining centers, drill presses, and manual machines configured for right-hand cutting tools.

Installation Notes

Installation is performed by machinists or CNC operators. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the chuck or collet. Verify chuck or collet runout is within tolerance before use, as excess runout accelerates carbide edge wear. Coolant-through is not supported on this drill; apply flood or mist coolant externally when machining materials that generate significant heat.
