The U624TM indexable drill is a compact drill body engineered for production environments, offering replaceable cutting inserts for economical high-volume holemaking.

• Ø28 mm cutting diameter
• 25 mm tool shank
• 112 mm cutting length
• Compatible with Korloy WCM-0503 inserts

Faster cycle times through focused geometry and replaceable cutting edges

The design centres on delivering consistent productivity: a 28 mm cutting diameter combined with a 112 mm cutting length provides a balance between hole depth capacity and rigidity. As an indexable drill, the unit eliminates full-tool replacement when cutting edges wear, shortening maintenance cycles and reducing tooling cost per hole. The use of standardised inserts keeps replenishment simple — the body accepts Korloy WCM-0503 inserts, allowing a workshop to rely on widely available cutting tips and minimise inventory complexity. This results in measurable efficiency gains on repetitive drilling operations in manufacturing and subcontracting environments.

Practical handling and reduced machine downtime

A focused shank specification contributes to secure clamping and predictable run-out. The 25 mm shank and 56 mm shank length enable stable fixing in common toolholders, while the moderate mass (0.662 kg) reduces spindle load without compromising stiffness. With replaceable edges rather than solid carbide tips, maintenance becomes a quick swap of inserts, which supports lean workflow practices on CNC machines and in manual drilling stations. The straightforward replaceability also helps sustain part tolerances across long batches, supporting consistent quality without prolonged stoppages.

Clear technical fit for workshop and CNC integration

The overall length of 196 mm and the shank dimensions are typical for drill bodies intended for both vertical machining centres and lathes with live tooling; these dimensions should be checked against the intended holder and reach requirements before selection. The construction is focused on clamp-and-go practicality: the centrepiece is the tool body that accepts indexable inserts, rather than a monolithic twist drill, so stocking compatible inserts and a suitable tightening key ensures rapid turnarounds. The compatibility with Korloy WCM-0503 inserts also simplifies the selection of grades for different workpiece materials where necessary.

Technical guidance for consistent hole quality

When planning a machining cycle, match the insert grade to the workpiece and set conservative feed rates for the first passes to verify chip evacuation and stability. The combination of 112 mm cutting length and the body geometry requires attention to support the workpiece and reduce deflection for deep holes. The 25 mm shank typically fits standard collets and holders; ensure the holder provides full contact length to maintain concentricity. Regular inspection of the insert seats and torqueing of the clamping screws will preserve alignment and help to achieve repeatable hole tolerances across production batches.

FAQ

Which inserts are compatible with this drill body?
The U624TM drill body is compatible with Korloy WCM-0503 indexable inserts, which are specified for the cutting edges of this model.

What are the main dimensions to check for toolholder compatibility?
Key dimensions are 28 mm diameter, 25 mm shank diameter and 196 mm overall length; these values determine holder selection and reach.

How long is the effective cutting length?
The effective cutting length is 112 mm, which indicates the working depth available for through-hole and shallow blind-hole applications.

What shank length should the clamping fixture accommodate?
The clamping fixture should allow for a 56 mm shank length to ensure full contact and stable clamping.

What is the unit weight for spindle load considerations?
The tool weighs 0.662 kg, which helps when calculating spindle load and dynamic balancing for high-speed operations.
