Osg 8690960 Screw Machine Drill Bit 9.6mm Carbide

Product Description

The OSG 8690960 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built to Series 6500 standards, it features a 9.6 mm (0.3780 inch) cutting diameter, a 140-degree split point, and an R-thinned web for reduced thrust and improved chip evacuation. The overall length is 106 mm (4.1732 inches) with a 48 mm flute length and a 10 mm straight-cylindrical shank. Coolant-through capability supports consistent performance at elevated cutting speeds. This bit is installed by machinists and tool-and-die professionals working in production or job-shop environments.

The 8690960 is suited for drilling steel, alloy steel, cast iron, titanium, and titanium alloys. Its screw machine length profile — shorter than jobber length — provides added rigidity in CNC machining centers, turret lathes, and drill presses where stub-length reach is adequate. The 3xD flute-to-diameter ratio and tapered web configuration support chip clearance in deeper entry passes. It is a practical choice for production drilling where tool life and hole quality in hard materials are priorities.

Key Features

• 9.6 mm cutting diameter with tolerance of +0 to -0.022 mm for consistent hole sizing
• 140-degree R-thinned point reduces walking and lowers entry thrust
• Solid carbide construction for heat resistance and extended tool life in ferrous and titanium workpieces
• Coolant-through design channels coolant directly to the cutting edge
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut, regular spiral with tapered web configuration for efficient chip evacuation

Compatibility

Designed for use in CNC machining centers, turret lathes, and drill presses that accept a 10 mm straight-cylindrical shank. Rated for primary workpiece materials including steel, alloy steel, cast iron, titanium, and titanium alloys. Fits within the 0.3500 to 0.4000 inch drill bit size range (9.50 to 11.00 mm range per Series 6500).

Installation Notes

Install and remove drill bits only with the spindle fully stopped and the machine in a locked-out, de-energized state per standard lockout/tagout procedures. Seat the shank fully and evenly in the collet or chuck before tightening to the tool holder manufacturer specification. Verify coolant lines are clear and flow is confirmed before initiating a cut. Inspect the cutting edges for chipping or wear before each use, as carbide is brittle and prone to edge damage if dropped or improperly stored.
