Maykestag Speedcut 4.0 Universal HPC Solid Carbide End Mill 20mm Long Series 4 Flute

Maykestag Speedcut 4.0 Universal HPC Solid Carbide End Mill 20mm

Professional 20mm long-series HPC end mill from the Maykestag Speedcut 4.0 Universal range, manufactured from VHM solid carbide and featuring 4 cutting flutes, Type N geometry, different 35°–38° spiral angles, a TWINDUR coating and a precision DIN 6535-HA shank.

The Maykestag Code 8217 Speedcut 4.0 Universal range is designed for high-performance milling across a broad selection of engineering materials. This 20mm cutter combines solid-carbide construction with a long-series DIN 6527 L design, four cutting flutes and different spiral angles of 35°–38°. The cutter is finished with Maykestag's TWINDUR coating and is manufactured with closely controlled cutting and shank tolerances for professional CNC and precision milling applications.

What is an HPC end mill? HPC stands for High Performance Cutting. An HPC end mill is designed for productive machining where cutting geometry, tool material, flute configuration and coating work together to provide controlled cutting performance at appropriately selected speeds and feed rates. The Speedcut 4.0 Universal Code 8217 combines solid-carbide construction with a multi-flute design and different spiral angles for professional milling applications. Product highlights

Why Choose Maykestag?

Maykestag develops professional cutting tools with carefully specified cutting geometry, dimensional tolerances, tool materials and application data. These details are especially important in CNC milling, where cutter rigidity, dimensional accuracy, cutting-edge consistency and correct cutting conditions all contribute to repeatable machining results.

The Code 8217 Speedcut 4.0 Universal series combines VHM solid carbide, TWINDUR coating, Type N geometry and different spiral angles in a long-series HPC end mill. Maykestag rates the range particularly highly for steels up to 1,100 N/mm² and for cast iron, while also providing suitability ratings for higher-strength steels, stainless steels, copper, brass and aluminium.

Designed for Universal HPC Milling

The Code 8217 range is specified with 3 to 4 flutes depending on cutter diameter. This 20mm version uses four flutes. Its 35°–38° different spiral-angle geometry forms part of the cutter's Speedcut 4.0 Universal HPC design. Combined with the rigid solid-carbide body, TWINDUR coating and precision DIN 6535-HA shank, the cutter is intended for accurate professional milling when used with suitable machine rigidity, tool holding and cutting data.
