Solid drill U787TM by Teknik Makina — Ø27 mm, compatible with WCM-0503 inserts

A solid drill body designed for indexable-insert drilling in general machining where deep, repeatable holes are required

• Solid drill body, Ø27 mm
• 25 mm shank diameter for secure clamping
• 135 mm cutting length for deep holes
• Compatible with WCM-0503 Korloy inserts

Stable drilling for repeatable hole quality

The body is engineered to provide stable, repeatable drilling in production and workshop settings. With a Ø27 mm cutting diameter and a long 135 mm cutting length, the design reduces the need for multiple operations when machining deep holes. The 25 mm shank offers a predictable clamping interface, which lowers runout and vibration; this translates directly into improved hole tolerances and fewer rejected parts. The specification-driven approach supports process planning and helps maintain cycle-time consistency on medium- to heavy-duty machines.

Quick indexable-insert handling to boost uptime

Compatibility with WCM-0503 inserts and the referenced Korloy system enables fast tool changes and low consumable costs. Using indexable inserts means that only the cutting tips are replaced when worn, rather than the entire tool, improving cost efficiency and reducing inventory burden. The interface for inserts is designed for straightforward seating and secure retention, delivering consistent geometry from one change to the next and shortening maintenance windows on the shop floor.

Balanced construction for everyday machining comfort

At 0.62 kg and an overall length of 218 mm, the tool body is balanced for stable handling and straightforward tool setup. The 56 mm shank length offers sufficient engagement for standard holders while allowing for compact clamping on many machining centres. The relatively low mass helps to reduce bearing load on spindle assemblies during longer runs, contributing to tool life and machine reliability. These mechanical attributes make the component suitable for both batch production and repair-shop environments where tool change frequency and ease of handling matter.

Practical fit for production and workshop supply chains

This solution is suited to manufacturers seeking a pragmatic compromise between performance and maintainability. The element’s clear numerical data — diameter, cutting length, shank dimensions and weight — make it simple to compare with existing holders and machining schedules. For procurement, the defined compatibility with Korloy inserts reduces uncertainty when selecting consumables, and the standardised dimensions aid integration into jigs and fixtures. The product supports efficient workflows and predictable maintenance cycles, aligning with Metav’s commitment to accessible precision.

FAQ

What insert types does this tool accept?
The tool accepts WCM-0503 indexable inserts; compatibility with Korloy insert grades is specified for consistent cutting performance with the solid drill U787TM.

Is the shank size suitable for standard tool holders?
Yes, the 25 mm shank diameter and 56 mm shank length are specified to match common clamping systems used in many machining centres and holders.

Can this tool be used for deep-hole drilling?
The 135 mm cutting length and Ø27 mm diameter make the tool suitable for deeper hole operations where a single-pass solution is preferred to reduce setup time.

Which manufacturer produced this tool and who supplies it?
The component is produced by Teknik Cutting Tools and supplied via Metav Werkzeuge; the SKU for ordering is U787TM.

How does insert use affect running costs?
Using indexable inserts such as WCM-0503 reduces running costs by limiting consumable replacement to the inserts only, improving cost-efficiency compared with one-piece tools.
