Kennametal 1913549 Screw Machine Drill Bit 13mm Carbide

Product Description

The KENNAMETAL 1913549 is a screw machine length drill bit engineered for high-performance drilling in demanding industrial applications. Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life in high-heat, high-speed environments. It measures 13.00 mm in diameter with an overall length of 107.00 mm (4.2126 inches) and features a 140-degree point angle designed for fast penetration and reduced thrust. The web-thinned, parallel web configuration minimizes cutting resistance at entry. This tool is installed and operated by machinists and tooling professionals running CNC screw machine or drill press operations.

This drill bit is suited for production drilling in cast iron and steel workpieces, including both light and heavy-duty machining environments. Its screw machine length profile makes it a practical choice in tight setups where a jobber-length bit would be too long. The straight cylindrical shank seats into standard toolholders or drill chucks. Coolant-through capability supports high-feed drilling cycles where internal cooling is available, helping to clear chips and manage heat at the cutting zone. The B976 series designation aligns this tool with Kennametal's DIN 6537K specification for short-length carbide drill bits.

Key Features

• Coolant-through design supports internal coolant delivery during high-feed operations
• Straight cylindrical shank compatible with standard chucks and toolholders
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-style tooling solution for screw machine and CNC drilling operations targeting cast iron and steel workpieces, per the B976 series specification under DIN 6537K.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup guidelines. Secure the shank fully within the toolholder or chuck to the specified grip depth before operation. Verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Always power down and lock out the machine before changing or adjusting tooling.
