Kennametal 1613657 Replaceable-tip Drill 28.17-28.67mm

Product Description

The KENNAMETAL 1613657 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM1109 insert tips at an Insert Seat Size 7, allowing fast tip changes without removing the body from the machine. The drill covers a diameter range of 28.17 to 28.67 mm (1.1091 to 1.2287 inches) with a maximum drill depth of 89.92 mm (3.54 inches), yielding a 3xD depth-to-diameter ratio. A Weldon Flat shank with a 31.75 mm diameter provides positive rotational drive in compatible tool holders. Through-coolant delivery is supported via NPT-threaded coolant ports, keeping cutting temperatures in check during deep-hole operations. Licensed machinists and CNC operators in production machining environments are the primary installers of this tooling.

This drill body is part of the KENNAMETAL KSEM series, engineered for high-productivity drilling in steel, cast iron, and similar ferrous workpiece materials. It is suited for horizontal machining centers, vertical machining centers, and CNC lathes with live tooling where a Weldon Flat tool holder is available. The 89.92 mm maximum drill depth and 124.97 mm flute length make it well matched for through-hole and blind-hole applications in medium to large component machining, such as hydraulic manifolds, engine blocks, and structural weldments requiring consistent, repeatable bore quality.

• Through-coolant design with NPT ports (body side 1/8-27 NPT, shank end 1/4-18 NPT)
• Weldon Flat shank, 31.75 mm diameter — positive anti-rotation drive
• Overall length 228.6 mm (9 inches) with 124.97 mm flute length for chip clearance

Compatibility

Designed for use with KSEM1109 replaceable insert tips, Insert Seat Size 7, within the KENNAMETAL KSEM series drill system. Requires a Weldon Flat tool holder with a 31.75 mm bore. No other specific compatible model numbers were provided in the product data.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before inserting or removing the drill body from the tool holder. Torque the Weldon Flat set screw according to your tool holder manufacturer specifications — no torque value is specified for this drill body. Verify through-coolant connections at both the body-side and shank-end NPT ports are clean and leak-free before running the spindle, and confirm insert tip seating before initiating a cut.
