Kennametal 1505171 Replaceable-tip Drill 17.46-17.96mm

Product Description

The KENNAMETAL 1505171 is a replaceable-tip drill body from the KSEM series, designed for high-productivity drilling in metalworking and machining applications. It accepts KSEM0688 insert tips at seat size 1, allowing worn or damaged cutting tips to be swapped out without replacing the entire tool body. The drill covers a diameter range of 17.46 to 17.96 mm (0.6874 to 0.7071 inches) and achieves a maximum drill depth of 90 mm (3.54 inches), representing a 5xD depth-to-diameter ratio. Overall length measures 184.15 mm (7.25 inches). Through-coolant delivery via 1/8-27 NPT ports at both the shank end and body side keeps heat controlled at the cutting zone during deep-hole operations.

This drill body is suited for CNC machining centers and turning centers in production environments where consistent hole diameter and depth repeatability are critical. It is typically used by machinists and tooling specialists in aerospace, automotive, die-and-mold, and general metalworking shops. The Weldon flat shank with a 19.05 mm diameter provides positive drive engagement in standard end-mill holders, reducing the risk of tool slip under heavy feed rates. The 5xD depth capability makes it applicable to through-holes and blind holes in a range of ferrous and non-ferrous workpiece materials depending on insert selection.

Key Features

• Replaceable KSEM0688 insert tip at seat size 1 — extend tool body life and reduce per-hole tooling cost

• 5xD depth-to-diameter ratio with 90 mm maximum drill depth
• Through-coolant design with 1/8-27 NPT ports at shank end and body side for effective chip evacuation and heat management
• 19.05 mm Weldon flat shank for positive, slip-resistant drive in standard holders
• Flute length of 111.25 mm (4.38 inches) supports chip clearance over the full working depth

Compatibility

Compatible with KSEM0688 replaceable insert tips at insert seat size 1. Part of the KENNAMETAL KSEM series drill body platform.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Ensure the Weldon flat shank is fully seated and the set screw in the holder is properly torqued per the holder manufacturer specifications before operation. Verify coolant passages are clear and the correct system pressure is applied before running through-coolant. Inspect the insert seat for debris or damage before seating a new KSEM0688 tip, and follow KENNAMETAL torque guidelines for the insert clamping screw.
