Sgs 51361 Screw Machine Drill Bit 15/32 in Solid Carbide

Product Description

The SGS 51361 is a screw machine length drill bit engineered for precision drilling in demanding industrial and machining applications. Built from solid carbide with a Ti-NAMITE-A AlTiN coating, this bit delivers exceptional heat resistance and wear life when cutting through alloy steels and titanium. The 145-degree notched point geometry reduces thrust and improves self-centering on entry. At 4-1/16 inches overall length, the screw machine format provides a rigid, short-length profile suited for CNC machining centers, drill presses, and turret lathes where stub-length stability is required. Machinists, tool and die makers, and production shop personnel are the primary users of this type of tooling.

This drill bit is designed for high-performance drilling in alloy steel and titanium workpieces where tool life and dimensional accuracy are critical. The 3xD flute-to-diameter ratio and tapered web configuration with web thinning help manage chip evacuation and cutting forces in deep-hole applications. The straight shank at 0.5000 inches diameter seats directly in standard drill chucks and collet holders. It is well suited to production environments running tight-tolerance hole programs where carbide tooling is specified over high-speed steel alternatives.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance in hard materials
• Ti-NAMITE-A AlTiN coating for high-temperature performance and extended tool life
• 145-degree notched point reduces entry thrust and improves hole location accuracy
• Web-thinned, tapered web configuration aids chip flow and reduces cutting force
• Screw machine length (3xD) profile provides stiffness in short-reach setups
• Right-hand cut with regular spiral flute geometry for consistent chip evacuation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide screw machine drill for production and job-shop applications requiring a 15/32 inch diameter straight-shank drill in alloy steel or titanium workpieces.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle and chuck or collet are fully de-energized and at rest before inserting or changing tooling. Seat the straight shank fully into the holding device and verify runout before initiating a cut. Follow shop-specific feeds and speeds for carbide tooling in the workpiece material being drilled; do not use this tool dry on materials requiring coolant unless the setup is confirmed compatible with the no-coolant-through design of this bit.
