Kennametal 1517235 Replaceable-tip Drill 23.81-24mm

Product Description

The KENNAMETAL 1517235 is a replaceable-tip drill body engineered for deep-hole drilling applications requiring consistent diameter control from 23.81 mm to 24 mm. Built on the KSEM platform, the drill accepts KSEM0938 inserts at an insert seat size 4, allowing quick tip changes without removing the body from the machine. The Weldon Flat shank measures 25.4 mm in diameter and provides positive rotational drive in compatible chucks and holders. Through-coolant delivery is supported via both body-side and shank-end coolant ports, keeping cutting zones clear during aggressive feed cycles. Licensed machinists and tooling technicians working in production or job-shop environments typically install and service this tool.

This drill body is suited for ferrous and non-ferrous material removal in CNC machining centers and drill presses where deep-hole performance at an 8xD depth-to-diameter ratio is required. The maximum drill depth reaches 190.5 mm, making it appropriate for through-holes and blind bores in medium-to-heavy workpieces. The tool is well matched to applications in automotive, aerospace, and general metalworking where repeatable hole geometry and fast insert indexing reduce downtime on high-volume runs.

Key Features

• Replaceable-tip design accepts KSEM0938 inserts at insert seat size 4 for fast, on-machine tip changes
• 8xD depth-to-diameter ratio supports maximum drill depth of 190.5 mm
• Weldon Flat shank at 25.4 mm diameter provides positive rotational drive and secure chuck engagement
• Through-coolant capability with body-side 1/8-27 NPT and shank-end 1/4-18 NPT coolant ports
• Overall length of 307.98 mm with a flute length of 216.06 mm for extended reach in deep-bore setups
• Part of the KSEM series, enabling insert commonality across multiple body sizes in a fleet

Compatibility

Compatible insert style is KSEM0938 at insert seat size 4. This drill body is designed as an OEM-style replacement or direct-fit tooling option within the KSEM series platform for CNC machining centers using Weldon Flat toolholders with a 25.4 mm bore.

Installation Notes

Installation and insert indexing should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked before any tip change or body mounting. Torque the insert per the tooling manufacturer's documentation included with the insert, not from memory. Verify coolant port connections are clear and sealed before resuming operation. Confirm the holder bore matches the 25.4 mm Weldon Flat shank specification before mounting.
