Sgs 66465 9.50mm Solid Carbide Screw Machine Drill Bit

Product Description

The SGS 66465 is a solid carbide screw machine length drill bit designed for high-performance drilling in a wide range of workpiece materials. It measures 9.50 mm (0.3740 inches) in diameter with an overall length of 3.5 inches and features a 135-degree split point for accurate self-starting without a center punch. The Ti-NAMITE-X coating extends tool life and supports operation in demanding production environments. With coolant-through capability and a web-thinned point geometry, this bit handles both light and heavy-cycle applications efficiently. It is suited for CNC machining centers, drill presses, and manual machines where precision and tool longevity are priorities.

This drill bit is built for use in production machining, toolroom, and maintenance applications across metalworking trades. The screw machine length body provides added rigidity compared to jobber-length bits, reducing deflection in harder materials. The straight-cylindrical shank at 10.00 mm (0.3900 inches) seats securely in standard drill chucks and collets. With a regular spiral flute and 4-margin design, it maintains consistent hole quality and concentricity. It is appropriate for use in ferrous and non-ferrous metals, plastics, and composite materials per its universal primary workpiece material rating.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in high-cycle applications
• Ti-NAMITE-X coating for extended tool life and heat resistance
• 135-degree web-thinned split point promotes accurate entry and reduces thrust force
• Coolant-through design directs fluid to the cutting zone for chip evacuation and thermal control
• 4-margin geometry supports tight hole tolerances and improved concentricity
• Conforms to DIN 6537 specification for dimensional consistency

Compatibility

Designed as a screw machine length replacement drill bit compatible with standard drill chucks and collets accepting a 10.00 mm straight-cylindrical shank. Fits CNC machining centers, knee mills, drill presses, and similar equipment configured for stub-length carbide tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or toolroom technician with the machine in a full stop, zero-energy state. Confirm chuck or collet bore size matches the 10.00 mm shank before seating the bit. Coolant-through setups require the spindle and coolant system to be properly connected and verified before running. Inspect the cutting edges and coating condition before each use; discard or resharpen bits showing chipping, crazing, or wear beyond the manufacturer threshold.
