Kennametal 1191132 Pilot Drill Head 78mm Hts Dft

Product Description

The KENNAMETAL 1191132 is a pilot drill head from the HTS DFT series, designed for deep-hole and large-diameter drilling applications. It accepts a B510S15000 fixed pilot drill with a 15mm pilot drill diameter and accommodates 4 non-pilot inserts held in cartridge-style insert holders. The head features a 22mm head connection size, a maximum drill diameter of 78mm (3.0709 inches), and a head length of 70mm (2.7559 inches). Coolant-through capability is built in, supporting consistent chip evacuation and tool life in demanding production environments. This head is installed by machinists and tooling specialists in CNC and manual drilling operations on industrial equipment.

The 1191132 is suited for large-diameter hole-making in metalworking applications where a pilot drill guides the cutting action before the outer inserts engage the workpiece. Typical use cases include production machining of steel and cast materials in job shop or manufacturing environments. The cartridge-style insert holding method allows for repeatable insert positioning and simplified indexing without removing the head from the machine. The head ships with an adjusting screw and clamping screw included.

Compatibility

Designed for use with HTS DFT series tooling systems using a 22mm head connection. Compatible pilot drill style is B510S15000 with a 15mm pilot drill diameter. Specific machine and holder compatibility should be verified against KENNAMETAL HTS DFT system documentation prior to ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle fully stopped before any head or insert changes. Confirm that the head connection size matches the boring bar or holder in use before mounting. Use the included adjusting and clamping screws per the manufacturer tooling assembly procedure. Coolant-through connections should be inspected for proper sealing before returning the tool to service.
