Osg 8595324 Screw Machine Drill Bit 3.24 Mm Tin Hss

Product Description

The OSG 8595324 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The 130-degree faceted point geometry promotes accurate entry and reduces walking on hard surfaces. At 3.24 mm in diameter and 50 mm (1.97 inches) overall length, this stub-length bit fits standard machining setups where rigidity and precision matter. It is installed and used by machinists, tool-and-die workers, and CNC operators working in production environments.

This drill bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, making it the preferred choice for drill press, turret lathe, and CNC machining center operations where runout control and hole accuracy are critical. The straight-cylindrical shank seats cleanly in standard chucks and collets.

Key Features

• TiN coating reduces friction and extends cutting life compared to uncoated HSS
• 130-degree faceted point for precise hole entry and reduced thrust force
• Web-thinned, tapered web construction lowers cutting resistance
• Regular spiral flute with 2 flutes for efficient chip evacuation
• Screw machine (stub) length provides added rigidity over jobber-length bits
• Right-hand cutting direction; compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement screw machine drill bit for use in standard straight-shank drill chucks and collets sized to accept a 4.00 mm shank diameter.

Installation Notes

This bit is installed by machinists and metalworking technicians using standard drill press, lathe, or CNC equipment. Ensure the machine spindle is fully stopped and de-energized before changing tooling. Secure the straight-cylindrical shank firmly in the chuck or collet to the manufacturer-specified clamping depth to prevent slippage. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, as this bit does not support coolant-through delivery.
