Sgs 63182 Screw Machine Drill Bit 8.40mm Carbide Altin

Product Description

The SGS 63182 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding materials. Built to Series 135M specifications, it features a 145-degree notched point angle with web thinning for reduced thrust and cleaner entry. The AlTiN finish — SGS Ti-NAMITE-A coating — provides heat resistance and extended tool life when cutting alloy steels and titanium. At 8.40 mm (0.3307 inch) diameter with a straight shank, this bit is suited for CNC machining centers and production drilling operations where tight tolerances and consistent performance are required.

This drill bit is intended for use on alloy steels and titanium workpieces in shop and production environments. The screw machine length format — shorter overall length with increased rigidity — makes it well suited for high-speed CNC applications where runout control and stability are critical. The regular spiral flute geometry handles chip evacuation in a wide range of metal-cutting setups. Licensed machinists and tool-and-die professionals commonly specify this format for precision hole production.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN (Ti-NAMITE-A) coating resists heat buildup in alloy steel and titanium cutting
• 145-degree notched point with web thinning reduces entry thrust and improves centering
• Screw machine length (3xD flute ratio) provides increased rigidity over jobber-length bits
• Right-hand cut with regular spiral flutes for reliable chip evacuation
• Tapered web configuration adds core strength along the flute length
• No coolant-through requirement — suitable for standard flood or dry cutting setups

Compatibility

Designed for use in applications requiring an 8.40 mm straight-shank drill bit with a 10.00 mm shank diameter, compatible with standard drill chucks and collet systems accepting that shank size. Primary workpiece materials are alloy steels and titanium.

Installation Notes

Installation and operation should be performed by qualified machinists following applicable shop safety protocols. Secure the straight shank firmly in a properly sized collet or drill chuck before operation, and verify runout is within acceptable tolerance for the application. Always power down and lock out the machine spindle before changing tooling. Do not exceed the recommended maximum drilling depth of 35.00 mm for this bit without retracting to clear chips.
