Kennametal 4149207 Jobber Drill Wire 12 Solid Carbide

Product Description

The KENNAMETAL 4149207 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Built to DIN 6537K standards, it carries a multilayer TiAlN coating that extends tool life in abrasive and heat-generating applications. The bit features a 140-degree point angle for reduced thrust and self-centering entry, a regular spiral flute geometry, and a straight cylindrical shank. Overall length is 3.228 inches (82.00 mm), with a flute length of 1.732 inches (44.00 mm). Coolant-through capability supports high-speed drilling cycles. This drill is specified and installed by machinists, toolroom technicians, and CNC operators working in production and job-shop environments.

The 4149207 is suited for drilling steel, stainless steel, cast iron, aluminum, and non-ferrous materials in both manual and CNC machine tool setups. Its 5xD flute-to-diameter ratio and tapered web configuration make it a practical choice for general-purpose production drilling where consistent hole quality and tool longevity are required. The wire size 12 designation corresponds to a decimal diameter of 0.1890 inches, placing it in the 0.1500 to 0.2000 inch diameter range.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating reduces heat buildup and extends service intervals
• 140-degree point angle lowers entry thrust and improves self-centering on flat and curved surfaces
• Coolant-through design supports high-feed drilling and chip evacuation in deep-hole applications
• DIN 6537K specification ensures dimensional interchangeability with standard toolholders
• Right-hand cut, regular spiral flute with tapered web for balanced chip flow

Compatibility

Designed as a DIN 6537K-compliant straight-shank jobber drill compatible with standard drill chucks and collet-style toolholders accepting a 0.1094-inch (6 mm) shank diameter. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the straight shank in a drill chuck or collet to the toolholder manufacturer's recommended clamping torque using calibrated tooling. Verify coolant-through passages are clear before initiating a drilling cycle. Handle carbide tooling carefully to avoid chipping the cutting edges during setup.
