SCMT09T304-E47 WPP20S drilling/reaming indexable insert by Walter Tools — Tiger·tec Silver, for steel

SCMT09T304-E47 WPP20S is a square 90° indexable insert designed for drilling and bore-enlarging operations, intended primarily for efficient machining of steel in production and workshop environments.

• Tiger·tec Silver coating for long tool life
• Grade WPP20S optimised for steel machining
• Square 90° shape for secure seating
• 0.4 mm corner radius for edge stability

Maximise productivity with proven cutting performance

The combination of the Tiger·tec Silver coating and the WPP20S carbide substrate provides a balance between wear resistance and toughness that reduces downtime and keeps cycle times steady. The insert is designed for the thermal and chip-formation behaviour typical of steel machining, so tool changes are less frequent and process stability improves. The integrated chipbreaker E47 supports continuous chip control, which lowers the risk of rework and machine stoppages — a direct benefit to production output and cost-efficiency.

Geometry and coating explained for dependable results

A 7° free angle and a 0.4 mm corner radius create a secure cutting edge that tolerates interruptions and maintains dimensional stability during bore enlargement. The square 90° form provides stable clamping in compatible tool holders and ensures predictable wear progression across indexed edges. The insert thickness T3 and the SCMT designation describe the geometry that matches common drilling/reaming tool bodies; these dimensions contribute to reliable seating and vibration resistance. The Tiger·tec Silver coating is a multilayer solution that improves oxidation resistance and preserves the cutting edge under elevated temperatures.

Practical application advice for workshops and small series production

This insert is assigned to ISO group P (steel), making it suitable for a broad range of unalloyed and alloyed steels encountered in general engineering. The grade allocation emphasises universality and wear resistance, which means fewer tool variants need to be stocked for mixed steel work. In practice, the insert performs well in bore finishing and light reaming passes where consistent surface quality and repeatable diameters are required. For optimisation, pairing the insert with a holder compatible with SCMT geometry and ensuring correct clamping torque will maintain accuracy and extend service life.

FAQ

What materials is this insert suitable for?
The SCMT09T304-E47 WPP20S insert is intended for ISO group P, specifically for unalloyed and alloyed steel, as indicated by its WPP20S grade and Tiger·tec Silver coating.

What does the SCMT09T304-E47 designation indicate?
The SCMT09T304-E47 code describes the insert geometry: square 90° shape, size 09, edge form E47 and the nominal thickness/execution suited to compatible tool holders.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating increases oxidation resistance and wear life, allowing the insert to maintain cutting-edge integrity under the heat and stresses typical of steel machining.

Is the corner radius suitable for interrupted cuts?
The 0.4 mm corner radius offers a compromise between edge strength and cutting precision, making it appropriate for many drilling and bore-enlarging applications that may involve slight interruptions.
