M.a. Ford. 2XDCL1378A Taper Length Drill Bit 3.5mm Carbide

Product Description

The M.A. FORD. 2XDCL1378A is a solid carbide taper length drill bit designed for precision drilling in demanding industrial and machining applications. Built to Series 2XDCL specifications, this bit features a 142-degree split point, a TiN (titanium nitride) coating, and a spiral flute configuration optimized for chip evacuation. The 3.5 mm diameter (0.1378 decimal inch) drill delivers consistent hole quality with a diameter tolerance of +0.000 to -0.012 mm. Coolant-through capability supports high-speed, deep-hole operations. Licensed machinists, tool-and-die technicians, and CNC operators handling tight-tolerance work rely on this bit for repeatable performance in ferrous and non-ferrous materials.

This drill bit is suited for use on CNC machining centers, drill presses, and multi-axis lathes in production and job-shop environments. It performs across a range of materials including cast iron, titanium, carbon steel, steel, and tool steel. The 7xD flute-length-to-diameter ratio and a maximum drilling depth of 35 mm make it well-matched for through-holes and moderate blind-hole applications in medium to hard workpiece materials. The straight cylindrical shank seats cleanly in standard collets and chucks without special tooling adapters.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard-material drilling
• TiN coating extends cutting edge life and reduces built-up edge in ferrous materials
• 142-degree drill point angle promotes accurate entry and reduces thrust force
• Coolant-through design supports chip flushing and tool cooling at depth
• 7xD flute-length-to-diameter ratio allows drilling up to 35 mm maximum depth
• Diameter tolerance of +0.000 to -0.012 mm for close-tolerance hole requirements

Compatibility

Designed as a taper length replacement or production drill for machining operations involving cast iron, titanium, carbon steel, steel, and tool steel workpieces. Fits standard collet chucks and drill chucks accepting a 4.00 mm straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with carbide tooling requirements. Ensure the machine spindle is fully stopped and the tool holder is clean and properly torqued before seating the bit. Solid carbide tooling is brittle and should not be used in setups with excessive runout or unsupported workpiece vibration, as chipping or fracture can result. Verify coolant flow through the spindle is active before beginning deep-hole cycles when using the coolant-through feature.
