Sumitomo U101097 Solid Carbide Mechanics Drill Bit 9/32

Product Description

The SUMITOMO U101097 is a solid carbide mechanics-length drill bit designed for high-performance drilling in demanding metalworking applications. Built to Series MDW-GS4 specifications, it features a TiAlCr/TiSi multilayer coating that extends tool life and manages heat during aggressive cuts. The 135-degree split point reduces thrust force and improves centering without a pilot hole. With an overall length of 3.2677 inches and a flute length of 1.6929 inches, this bit is sized for close-tolerance work in machining centers, CNC equipment, and manual drill presses. It is installed by machinists, tool-and-die technicians, and maintenance mechanics working with hard and abrasive metals.

This drill bit is engineered for use in cast iron, non-ferrous metals, stainless steel, and carbon and alloy steels, covering ISO material groups H, K, M, N, P, and S. The mechanics-length body provides rigidity and reduced deflection compared to jobber-length drills, making it well suited for production environments where hole position and roundness are critical. It is sold as a single-piece unit and is appropriate for both manual and CNC drilling setups requiring consistent, repeatable results.

Key Features

• Solid carbide construction delivers superior rigidity and wear resistance compared to HSS tooling
• TiAlCr/TiSi multilayer coating improves heat resistance and extends tool life in ferrous and hard materials
• 135-degree split point promotes self-centering and reduces entry thrust force
• Tapered web configuration adds core strength and supports aggressive feed rates
• Mechanics-length body minimizes deflection for tight-tolerance hole drilling
• Compatible with cast iron, stainless steel, non-ferrous metals, and carbon and alloy steels

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual drilling equipment requiring a 9/32 inch solid carbide mechanics drill bit with a 0.2812 inch shank diameter.

Installation Notes

This drill bit is installed by machinists and maintenance mechanics in chuck-equipped drilling equipment. Ensure the machine spindle and chuck are clean and properly sized for the 0.2812 inch shank before seating the bit. Power down and lock out the machine before inserting or removing tooling. Do not exceed the machine manufacturer's recommended feed and speed parameters for the workpiece material being drilled.
