Sgs 56433 Screw Machine Drill Bit 21/32 Solid Carbide

Product Description

The SGS 56433 is a screw machine length drill bit engineered for high-performance drilling in a wide range of workpiece materials. Built from micrograin solid carbide with a proprietary coated finish, it delivers exceptional hardness and wear resistance in demanding production environments. The bit measures 0.6562 inches (21/32 inches) in diameter with an overall length of 4.8425 inches and a flute length of 2.874 inches. A 135-degree drill point angle and web-thinned tip reduce entry force and improve centering accuracy. Coolant-through design supports high-feed drilling operations where heat management is critical. Machinists, toolroom technicians, and CNC operators working in metalworking and fabrication applications are the primary users of this tool.

The SGS 56433 is suited for production drilling in machining centers, drill presses, and CNC lathes where short, rigid tooling is preferred over jobber-length bits. The screw machine length format reduces tool overhang, improving rigidity and hole accuracy in tight setups. With a 3xD flute-to-diameter ratio and right-hand spiral flute geometry, it handles a broad range of universal workpiece materials. The straight cylindrical shank fits standard tool holders and collet chucks without modification. Four margins provide enhanced hole wall finish and straighter hole geometry compared to standard two-margin designs.

Key Features

• Micrograin solid carbide construction for high hardness and extended tool life
• Coolant-through design enables effective heat and chip management at elevated feed rates
• Web-thinned 135-degree drill point reduces thrust force and improves self-centering
• Four-margin geometry delivers tighter hole tolerances and improved wall finish
• Screw machine length body increases rigidity and reduces deflection in short-reach setups
• Meets DIN 6537 specification for consistent dimensional standards

Compatibility

Designed as a direct-fit screw machine length drill bit for standard straight-shank tool holders and collet chucks used in CNC machining centers, drill presses, and lathes requiring a 21/32-inch diameter bore.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify that the collet or chuck is rated for the 18.001 mm shank diameter before clamping. When using the coolant-through feature, confirm that the machine coolant system pressure is appropriate for the application before initiating the cut.
