WCGT020102-X25 WK1 — Drilling/Boring indexable insert, Trigon 80°, WK1 by Walter Tools

The WCGT020102-X25 WK1 is a trigon 80° indexable insert designed for drilling and bore-enlargement operations where controlled chip flow and repeatable edge performance are required

• Trigon 80° geometry for axial stability
• Uncoated carbide grade WK1 for predictable wear
• Chipbreaker X25 for reliable chip control
• 0.2 mm corner radius for fine finishing

Consistent hole quality through optimised geometry

The trigon geometry with an 80° form and a 0.2 mm corner radius provides a balance between strength and precision, reducing the risk of burr formation while maintaining axial stability in holemaking. The chipbreaker X25 is engineered to manage micro‑chips effectively, which helps to avoid long, stringy swarf that can interrupt production. For users unfamiliar with insert classification, the WK1 designation denotes an uncoated carbide grade intended for general machining; the exact material suitability should be confirmed against the product matrix to ensure the grade matches the workpiece and cutting conditions.

Predictable productivity and process security

The combination of a robust geometry and the WK1 carbide grade supports steady cutting forces and predictable edge wear, which contributes to reduced stoppages and more consistent cycle times. This rational performance advantage is particularly relevant in batch production or mixed‑series machining, where repeatability is essential. Where process optimisation is sought, pairing the insert with the correct holder and cutting data will enhance tool life and surface finish. The Walter Tools pedigree reinforces the expectation of consistent tool life and process reliability.

Practical handling and integration into existing toolsets

The insert is supplied in a compact Trigon 80° format with design codes that match common drilling/boring toolholders. The listed codes indicate form and seat compatibility; for example, size code 02 and plate thickness 01 correspond to standardised insert dimensions. The 7° clearance angle supports contact reduction at the flank, improving tool engagement in bore operations. For mounting and clamping, use the recommended carrier and torque values; improper seating can lead to oscillation or premature wear. When machining exotic or heat‑resistant alloys, verify compatibility since the WK1 grade is an uncoated option and may not suit all high‑temperature materials.

What to expect in cutting performance and finish

Users can expect steady chip formation and a balanced trade-off between edge strength and finish quality. The 0.2 mm radius allows for close tolerance finishing where small radii help achieve smoother bore walls. While the insert provides a good baseline for a wide range of materials, adjustments to feed and speed are often necessary to reach optimum surface quality. If higher thermal resistance or extended life is required, consider coated grades or alternative manufacturers’ grades—bearing in mind the insert’s intended purpose and the Walter design philosophy that aims for stable cutting edges and controlled chip formation.

FAQ

What operations is this insert suitable for?
The WCGT020102-X25 WK1 insert is designed for drilling and bore‑enlargement operations where trigon geometry and the X25 chipbreaker support axial stability and controlled chip flow.

Is the WK1 grade suitable for stainless applications?
The WK1 grade is an uncoated carbide; suitability for rostfreier Stahl or other specific materials should be confirmed using the product matrix and cutting data, as material compatibility depends on workpiece alloy and machining conditions.

What does the X25 chipbreaker do?
The X25 chipbreaker is engineered to fragment and guide chips during cutting, improving chip evacuation and reducing the likelihood of swarf entanglement in bore operations.

Can this insert be used for finishing passes?
With its 0.2 mm corner radius, the insert can achieve improved surface finish in many bore applications, but final results depend on feed, speed, and holder rigidity.

How should the insert be mounted?
Use the correct Walter Tools holder specified for Trigon 80° inserts and follow the manufacturer’s clamping and torque recommendations to ensure seating integrity and repeatable performance.
