Sgs 63168 Solid Carbide Drill Bit 5.00 Mm 145 Degree

Product Description

The SGS 63168 is a screw machine length drill bit engineered for high-performance drilling in demanding materials. Built from solid carbide and finished with an AlTiN (Ti-NAMITE-A) coating, this bit delivers heat and wear resistance needed when cutting alloy steels and titanium. The 145-degree notched point geometry promotes self-centering and reduces thrust force at entry. At 5.00 mm (0.1969 inches) in diameter with a 66.00 mm (2.5984 inches) overall length, the stub-length design increases rigidity and minimizes deflection. Right-hand cut with a regular spiral flute pattern, the 63168 is a Series 135M tool suited for CNC machining centers, drill presses, and manual production setups where precision hole tolerances are required.

This drill bit is intended for use in metalworking applications involving alloy steels and titanium workpieces. The screw machine length format makes it well-suited for close-quarter drilling operations and applications where standard jobber-length bits introduce excessive runout or chatter. The straight shank at 6.00 mm (0.2362 inches) in diameter fits standard drill chucks and ER collet systems commonly used in production machining. A maximum drilling depth of 20.00 mm and a flute-to-diameter ratio of 3xD make this an efficient choice for shallow-to-medium depth hole applications in tight tolerances.

Key Features

• Solid carbide construction provides superior rigidity and wear life versus high-speed steel in hard materials
• AlTiN (Ti-NAMITE-A) coating enhances heat resistance and extends tool life in dry or minimal-lubrication cutting
• 145-degree notched point with web thinning and tapered web configuration reduces thrust and improves chip evacuation
• Screw machine (stub) length design increases stiffness and reduces deflection in precision hole applications
• Regular spiral flute with 2 margins promotes consistent chip flow and hole finish
• Straight shank compatible with standard chucks and collet systems; no adapter required

Compatibility

Designed for drilling alloy steels and titanium workpieces. The 6.00 mm straight shank fits standard drill chucks and ER collet holders used in CNC machining centers and production drill presses. Part of the SGS Series 135M screw machine length carbide drill line.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and chuck or collet are clean and properly torqued before operation. Carbide tooling is brittle and should not be used in machines with excessive spindle runout or in hand-held drilling applications. Confirm drilling depth does not exceed the rated maximum depth of 20.00 mm to avoid flute packing and tool breakage.
