CPGT050204-X25 WK1 — Drill/Boring Indexable Insert by Walter Tools, Rhombus 80° / 11° clearance

CPGT050204-X25 WK1 is an indexable cutting insert for drilling and bore-enlargement applications, designed to provide stable chip control and consistent hole quality in general machining.

• Uncoated carbide grade WK1
• Rhombus 80° insert geometry
• 0.4 mm corner radius
• 11° clearance angle

Consistent chip control for higher process reliability

The uncoated carbide composition of the insert, specified as WK1, promotes stable behaviour under varied machining conditions. Thanks to the chipbreaker X25, the insert reduces long, stringy chips and supports regular chip segmentation, which simplifies chip evacuation and reduces the risk of interruptions. This results in fewer machine stops and a more predictable cycle time, supporting continuous production where reproducible performance matters.

Geometry engineered for machining accuracy and tool life

The Rhombus 80° form combined with an 11° clearance angle and a 0.4 mm corner radius balances cutting strength and dimensional control. The geometry delivers improved edge support for bore-facing and enlargement tasks while the modest corner radius helps maintain hole tolerance without excessive cutting forces. The clearances and shape work together to extend edge life under moderate loads, improving overall machining economy and reducing insert change frequency.

Practical fitment and material guidance for reliable selection

The insert is offered in the catalogue-dependent material variants and sits in the Walter cutting grade series – open; users should verify the grade match for specific workpiece materials via the product matrix. The insert’s designation indicates form and chipbreaker compatibility with standard drilling and boring toolholders; tolerance class G denotes consistent manufacturing quality. For multi-material shops, this insert is suitable where uncoated carbide performance is preferred and toolholders accept Rhombic 80° indexable inserts.

FAQ

What cutting grade is WK1 and what does it mean for machining?
WK1 is an uncoated carbide grade from Walter Tools; the grade in the CPGT050204-X25 WK1 insert offers stable edge behaviour suitable for general-purpose drilling and bore-enlargement where coated grades are not required.

Which hole-making operations suit this insert?
The insert is designed for drilling and bore-enlargement operations; its Rhombus 80° geometry and chipbreaker X25 make it appropriate for controlled chip formation during hole cutting and reaming-adjacent passes.

How should the corner radius and clearance angle be interpreted for process setup?
The 0.4 mm corner radius provides a compromise between edge strength and dimensional accuracy, while the 11° clearance angle reduces rubbing on the flank, together helping to maintain hole tolerance and extend edge life.

Is this insert compatible with standard drill and boring holders?
Yes, the designation CPGT050204-X25 indicates an indexable insert form and chipbreaker suited to common drill and boring toolholders that accept Rhombic 80° inserts; check the holder’s insert seat for size code 05 and thickness code 02.

What documentation should be consulted before selection?
Refer to the Walter Tools product matrix for the CPGT050204-X25 WK1 to confirm workpiece material suitability and recommended cutting parameters; the insert’s series information notes that material variants are catalogue-dependent.
