Kennametal 1505115 Replaceable Tip Drill Ksem Series

Product Description

The KENNAMETAL 1505115 is a replaceable-tip drill body from the KSEM series, designed for precision hole-making in metalworking and machining applications. It accepts KSEM0813 insert tips at an insert seat size 3, covering a drill diameter range of 20.64 to 21.14 mm (0.8126 to 0.8323 inches). Maximum drill depth is 66 mm (2.60 inches), with a 3xD depth-to-diameter ratio. The shank is a 25.4 mm Weldon Flat configuration, providing positive drive engagement in compatible tool holders. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone for chip evacuation and thermal management. A licensed machinist or CNC tooling specialist installs and sets this drill body.

The 1505115 is suited for production drilling in ferrous and non-ferrous materials on CNC machining centers and drill presses equipped with Weldon flat tool holders. The replaceable-tip system allows tip indexing without removing the drill body from the spindle, reducing downtime in high-volume applications. Typical use cases include through-hole and blind-hole drilling in workpieces requiring consistent, accurate bore diameters in the 20.64 to 21.14 mm range. The drill body itself remains in the spindle while worn KSEM0813 tips are swapped at the machine, making it a practical choice for shops running repeated hole patterns.

Key Features

• Accepts KSEM0813 replaceable tips at insert seat size 3 for fast tip changes without full tool removal
• Through-coolant design with NPT-threaded coolant ports: body side 1/8-27 NPT, shank end 1/4-18 NPT
• Weldon Flat shank (25.4 mm diameter) provides secure, anti-rotation drive in standard tool holders
• 3xD depth-to-diameter ratio supports drill depths from 60 to 80 mm depending on insert selection
• Overall length of 190.5 mm (7.5 inches) with a flute length of 92.46 mm (3.64 inches)
• KSEM series platform enables consistent diameter coverage across a broad range of tip options

Compatibility

Designed for use with KSEM0813 series replaceable drill tips at insert seat size 3. Requires a tool holder or spindle accepting a 25.4 mm Weldon Flat shank. Compatible with machining centers supplying through-spindle or body-side coolant at standard NPT fittings.

Installation Notes

Installation and tip changes should be performed by a qualified machinist following the machine tool manufacturer's tooling procedures. Disengage spindle power and verify the machine is in a safe, locked-out state before inserting or removing the drill body or replacing tips. Ensure coolant line connections match the NPT thread sizes at the shank end and body side ports before pressurizing the coolant system. Consult the KENNAMETAL KSEM tooling guide for recommended tip torque and runout tolerance specifications before first use.
