SPHT09T308-G88 WK10 — SPHT09T308-G88 indexable milling insert (square 90°, 11° clearance) — Walter Tools

A precision SPHT09T308-G88 WK10 indexable milling insert designed for general milling tasks where stable chip formation and consistent edge life are required

• Square 90° geometry for robust milling
• 11° clearance for stable cutting
• G88 chipbreaker for improved chip control

Predictable chip control for fewer interruptions

The insert features the G88 chipbreaker, engineered to break and evacuate chips consistently under typical milling conditions; this reduces downtime caused by chip entanglement and supports continuous operation. With controlled chip formation, tool change intervals become more predictable and machine uptime improves. The result is a measurable contribution to cycle-time reliability and a smoother production flow, particularly in mixed-batch applications.

Geometry engineered for strength and process stability

A 90° square form factor combined with an 0.8 mm corner radius provides a sturdy cutting edge that resists chipping during intermittent cuts and interrupted milling. The 11° clearance angle reduces rubbing on the flank face, lowering cutting forces and heat generation. These geometrical choices translate into stable cutting conditions and reduced vibration, which helps to maintain dimensional accuracy on prismatic components.

Practical specifications that simplify tooling decisions

The insert is supplied in a T3 thickness format and the marking SPHT09T308-G88 identifies its size and chipbreaker variant, allowing straightforward selection for existing toolholders. The square shape gives multiple indexable edges per insert, supporting economical edge utilisation. As an uncoated WK10 grade (uncoated carbide), it suits a range of typical workshop tasks where coating is not required; verify the material matrix for the intended workpiece to confirm suitability.

Grade information and application guidance

The WK10 grade denotes an uncoated cemented carbide formulation intended for general-purpose use; it offers a balance of toughness and wear resistance for a wide material spectrum. For specific components or advanced alloys, check the product matrix and consider process parameters such as feed, speed and depth of cut to exploit the insert’s chip control and geometry. When process stability and repeatability matter, pairing this insert with a properly matched cutter body yields consistent surface finish and tool life.
