Sandvik Coromant 5747942 Solid Carbide Jobber Drill 15/64 Inch

Product Description

The SANDVIK COROMANT 5747942 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding industrial and machining applications. Built to DIN 6535HA standards, it features a 15/64 inch (3.90 mm) diameter, a 140-degree self-centering point, and a TiAlN coating for extended tool life under high-heat cutting conditions. The 2-flute spiral design and micrograin carbide substrate deliver consistent chip evacuation and edge stability. The straight-cylindrical shank measures 0.2362 inches in diameter, and the overall length is 2.5984 inches. This drill is classified as a high-performance grade tool suited for production-volume drilling where repeatability and precision are critical.

This drill is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. It belongs to the Series R840 product family, a line engineered for high-speed, coolant-through drilling in CNC machining centers and similar equipment. The flute-to-diameter ratio is 5xD, with a maximum drilling depth of 1.1024 inches (20.00 mm). Internal coolant-through capability supports chip flushing and heat management during deep or continuous drilling cycles in automated setups.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in hard and abrasive materials
• TiAlN coating reduces heat buildup and extends tool life in ferrous and exotic alloy cutting
• 140-degree self-centering point eliminates the need for center-drilling in most CNC applications
• Coolant-through design supports internal chip evacuation and thermal control at the cutting edge
• Straight-cylindrical shank with 6.00 mm diameter for standard ER and hydraulic chuck compatibility
• DIN 6535HA specification ensures dimensional consistency across replacement and multi-spindle setups

Compatibility

The 5747942 belongs to the SANDVIK COROMANT Series R840 and is designed for CNC machining centers and drilling equipment with coolant-through spindle capability. It is suited for ISO material groups P, M, K, N, and S as stated by the manufacturer. No additional specific machine model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the straight-cylindrical shank in a properly sized collet chuck or hydraulic toolholder and verify runout before production use, as carbide drills are sensitive to lateral loading from misalignment. Confirm that machine spindle coolant-through pressure is within the toolholder and spindle specification before enabling internal coolant flow. Do not use this drill in hand-held drilling equipment, as solid carbide tooling requires rigid, vibration-controlled setups to avoid brittle fracture.
