Kennametal 4149217 Jobber Drill Wire 3 Solid Carbide

Product Description

The KENNAMETAL 4149217 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It carries a wire gauge size of 3, equivalent to 0.2130 inches in decimal, and features a 140-degree split point that reduces walking and improves penetration on hard materials. The multilayer TiAlN coating extends tool life by resisting heat and wear at elevated cutting speeds. With an overall length of 3.2283 inches and a flute length of 1.7323 inches, this bit is built for precision through-hole drilling in production environments. Installation and operation are handled by machinists and CNC operators working to DIN 6537K specification standards.

This drill bit is suited for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its coolant-through design makes it particularly effective in CNC machining centers where internal coolant delivery is available, helping to evacuate chips and manage heat during deep-hole operations. The 5xD flute-to-diameter ratio supports a maximum drilling depth of 1.3780 inches. It is a strong fit for high-volume production shops, tool rooms, and job shops requiring consistent dimensional accuracy on tight-tolerance bores.

Key Features

• Solid carbide construction provides rigidity and wear resistance superior to high-speed steel in hard-material applications
• 140-degree point angle reduces thrust force and minimizes workpiece deformation on entry
• Multilayer TiAlN coating improves heat resistance and extends tool life at aggressive feed and speed parameters
• Coolant-through capability supports internal coolant delivery for chip evacuation and thermal management
• DIN 6537K specification ensures dimensional consistency and interchangeability with compatible toolholders
• Right-hand spiral flute with tapered web configuration promotes efficient chip flow and stable cutting geometry

Compatibility

Designed as a DIN 6537K-specification jobber drill for use in CNC machining centers and drill presses with straight-shank toolholders accepting a 0.2969-inch shank diameter. Compatible primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

This drill bit is installed and operated by machinists and CNC setup technicians. Before mounting, verify that the toolholder bore and collet are clean and free of debris to ensure accurate runout. Confirm that the machine spindle is fully stopped and the control is in a safe state before inserting or removing the tool. When using the coolant-through feature, ensure the machine coolant system is primed and set to the appropriate pressure for the cutting application before beginning the cycle.
