Kennametal 1798205 Replaceable-tip Drill Ksem 14.29-14.5mm

Product Description

The KENNAMETAL 1798205 is a replaceable-tip drill body in the KSEM series, designed for high-productivity hole-making in metal cutting applications. It accepts KSEM0563 insert tips seated at an Insert Seat Size B position, allowing the cutting tip to be swapped without removing the drill body from the machine. The body covers a drill diameter range of 14.29 to 14.5 mm (0.5626 to 0.5709 inches) and reaches a maximum drill depth of 100.01 mm (3.94 inches), representing a 7xD depth-to-diameter ratio. A straight-cylindrical shank of 19.05 mm diameter and through-coolant capability make this body suitable for CNC machining centers and lathes where coolant delivery at the cutting zone is required.

This drill body is intended for use in production machining environments where consistent hole quality and reduced tooling changeover time are priorities. The replaceable-tip design eliminates the need to regrind or discard the entire drill body when the cutting edge wears. Typical applications include drilling in carbon steels, alloy steels, and similar ferrous materials on CNC vertical and horizontal machining centers. The through-coolant feature supports chip evacuation in deep-hole drilling scenarios within the 7xD depth range.

Key Features

• Replaceable KSEM0563 insert tip - cutting edge replaced without removing the body from the spindle
• Through-coolant design aids chip evacuation and extends insert life in deep drilling operations
• 7xD depth-to-diameter ratio supports holes up to 100.01 mm deep relative to the 14.29 to 14.5 mm diameter range
• Straight-cylindrical shank at 19.05 mm diameter for standard ER or hydraulic chuck toolholding
• 168.28 mm overall length with a 114.55 mm flute length for clearance in most machining center setups
• Insert Seat Size B for positive tip location and repeatable runout on size changeovers

Compatibility

The 1798205 drill body is compatible with KSEM0563 replaceable insert tips and is part of the KSEM series platform. Insert Seat Size B is required for proper tip seating and clamping on this body.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine in a full stop and lockout-tagout procedure applied before handling the spindle or toolholder. Seat the insert tip according to the torque guidance provided in the KENNAMETAL KSEM assembly documentation, using the correct Torx key - do not substitute a non-specified driver. Verify coolant passages are clear and coolant pressure is within the machine specification before running the drill. Confirm runout at the insert tip with a dial indicator before cutting to ensure the body is correctly seated in the toolholder.
