Kennametal 2217005 Screw Machine Drill Bit 7.70mm Carbide

Product Description

The KENNAMETAL 2217005 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous and cast metal workpiece materials. Built to DIN 6537K standards, it features a 7.70 mm (0.3031 inch) cutting diameter, a 140-degree split point, and a TiAlN coating that extends tool life in demanding production environments. The web-thinned, parallel web geometry reduces thrust load at entry. With an overall length of 79.00 mm (3.1102 inches) and a flute length of 41.00 mm, this short-length design provides rigidity for precise, repeatable hole location in machine tool applications.

This drill bit is suited for CNC machining centers, drill presses, and automated production equipment where screw machine length drills are specified for rigidity and accuracy. Primary workpiece materials include cast iron and steel. The straight cylindrical shank measures 8.00 mm in diameter and seats cleanly in standard chucks and collet holders. It is a single-unit item intended for professional machinists and toolroom technicians working in metalworking and manufacturing environments. Maximum drilling depth is rated at 29.00 mm per the manufacturer specifications.

Key Features

• Solid carbide construction in Kennametal KC7315 grade for rigidity and heat resistance
• TiAlN coating extends cutting life in cast iron and steel applications
• 140-degree standard point angle with web-thinned geometry to reduce entry thrust
• Screw machine (stub) length body provides maximum rigidity for close-tolerance work
• Right-hand cutting, 2-flute regular spiral design for efficient chip evacuation
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-style tooling replacement for screw machine length drill applications in CNC and manual metalworking equipment accepting a straight cylindrical shank of 8.00 mm diameter. Part of the Kennametal B966A series, Dynapoint High Performance grade, covering the 6.50 mm to 8.00 mm drill bit size range.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before changing tooling, de-energize the machine and confirm spindle rotation has fully stopped. Seat the straight shank fully into the chuck or collet holder and confirm runout is within tolerance before beginning a cut. No coolant-through capability is present on this drill; ensure external coolant or cutting fluid is applied as appropriate for the workpiece material and cutting parameters.
