Sandvik Coromant 5747883 Solid Carbide Jobber Drill 11/32 in

Product Description

The SANDVIK COROMANT 5747883 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding metalworking applications. Built to Series R840 standards and conforming to DIN 6535HA, this drill features a 140-degree self-centering point geometry and a TiAlN coating that extends tool life under elevated cutting temperatures. The 11/32-inch (0.3437-inch decimal) cutting diameter is paired with a 0.3937-inch straight-cylindrical shank, making it compatible with standard drill chucks and tool holders. With through-coolant capability and a regular spiral flute design, it delivers consistent chip evacuation and thermal control during extended cuts. Micrograin carbide substrate and high-performance grade classification make this drill suitable for production environments where consistency and tool longevity are priorities.

This drill is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering material groups P, M, K, N, and S. It is well suited for CNC machining centers and drill presses where precise, repeatable hole quality is required. The 8xD flute-by-diameter ratio supports drilling to a maximum depth of 2.9528 inches, making it appropriate for deep-hole passes in a single setup. Machinists and toolroom technicians working in job shops, aerospace component manufacturing, and general metalworking will find this drill a reliable choice for tight-tolerance bore requirements.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlN coating reduces heat buildup and extends tool life in steel, stainless steel, and superalloy cuts
• 140-degree self-centering point eliminates the need for a center drill in most applications
• Through-coolant capability supports chip flushing and thermal management at full drilling depth
• DIN 6535HA straight-cylindrical shank ensures secure clamping in standard ER collets and drill chucks
• Regular spiral flute with 8xD depth ratio allows deep-hole drilling without peck cycles on suitable setups

Compatibility

Designed for use in CNC machining centers, drill presses, and multi-axis machines equipped with standard straight-shank tool holders or ER collet systems accepting a 0.3937-inch shank diameter. Rated for workpiece materials coded P, M, K, N, and S per ISO material classification.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle powered down and locked out per facility lockout/tagout procedures. Confirm collet or chuck bore matches the 0.3937-inch shank diameter before clamping to prevent runout. When enabling through-coolant, verify that the machine spindle and tool holder are rated for coolant-through operation and that coolant pressure is set per machine tool specifications. Inspect the cutting edge and coating condition before each use; do not run a chipped or delaminated carbide drill at production feeds and speeds.
