Kennametal 1127907 Pilot Drill Insert 8mm Hts Dft

Product Description

The KENNAMETAL 1127907 is an 8mm diameter pilot drill insert designed for use in HTS DFT modular drilling systems. Manufactured from high speed steel (HSS) with a Titanium Nitride (TiN) coating, this insert delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. It carries the Manufacturer Grade AS3 designation and is produced in the B510 insert style. The 118-degree point angle is a general-purpose geometry suited for a wide range of workpiece materials. This insert is installed and serviced by machinists, tool-and-die technicians, and CNC operators in production and job-shop environments.

This pilot drill insert is intended for use in KENNAMETAL HTS DFT modular drill bodies that accept the B510 insert style. The HTS DFT system is commonly applied in through-hole and blind-hole drilling operations on machining centers and CNC lathes. It is appropriate for steel, cast iron, and similar ferrous workpiece materials where a general-purpose HSS insert with TiN coating provides adequate tool life. The insert is sold individually and is a direct replacement component within the HTS DFT system, making it a practical choice for shops that maintain their own tooling inventory.

Key Features

• 8mm cutting diameter in the B510 insert style for HTS DFT modular drill bodies
• High speed steel construction provides toughness and resistance to chipping at the cutting edge
• Titanium Nitride (TiN) coating increases surface hardness and extends tool life in ferrous materials
• 118-degree point angle is a proven general-purpose geometry for a broad range of materials
• Manufacturer Grade AS3 designation for consistent dimensional and performance standards
• Sold as a single insert, allowing targeted replacement without discarding the full drill body

Compatibility

Designed for use with KENNAMETAL HTS DFT modular drill bodies that accept the B510 pilot drill insert style.

Installation Notes

Insert replacement is performed by machinists or tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped, locked out, and the tool body is secured in a vise or proper holder to prevent movement. Use the correct insert clamp screws and tightening tool as specified for the HTS DFT body to achieve proper seating. Inspect the insert pocket and clamping surfaces for chips or debris before installing the new insert.
