Emuge TA219744.1270 Solid Carbide Jobber Drill 1/2 Inch

Product Description

The EMUGE TA219744.1270 is a solid carbide jobber-length drill bit designed for high-performance hole-making across a wide range of materials. Built to DIN 6537 L standards, it features a 140-degree self-centering point and a TiAlN coating that extends tool life in demanding cutting environments. The straight-cylindrical shank measures 0.5512 inches in diameter, and the overall length comes in at 4.8819 inches. Coolant-through capability supports chip evacuation and heat management during deep-hole applications. This drill is suited for use in CNC machining centers and is typically installed and operated by machinists and tooling professionals working in production or job-shop environments.

The TA219744.1270 is appropriate for both ferrous and non-ferrous workpiece materials, consistent with its Universal primary workpiece material designation. The 5xD flute-to-diameter ratio and web-thinned, tapered web configuration allow for efficient chip flow in moderate-depth drilling applications up to 2.3622 inches deep. A double-margin design improves hole quality and drill stability. This bit fits standard CNC spindles and manual drill presses equipped to accept a 0.5512-inch straight-cylindrical shank, making it a practical choice in precision manufacturing, aerospace, automotive, and general metalworking applications.

Key Features

• Solid carbide sub-micrograin construction for rigidity and wear resistance
• TiAlN coating for heat resistance and extended tool life
• 140-degree self-centering point reduces walking and improves positional accuracy
• Coolant-through design supports chip removal and thermal control at depth
• Double-margin geometry improves hole roundness and surface finish
• Web-thinned tapered web lowers thrust force requirements at entry

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for setups requiring a 1/2-inch straight-cylindrical shank jobber drill conforming to DIN 6537 L in the TA219744 series.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Ensure the spindle and collet or chuck are clean and properly torqued to manufacturer specifications before use. Power down and lock out the machine before changing tooling. Avoid running carbide drills at feed and speed parameters set for high-speed steel, as carbide requires adjusted cutting data to prevent chipping or fracture.
