MAYKESTAG HSS-Co8 Morse Taper Shank Drill 28mm Short Series Steamed

Maykestag HSS-Co8 Morse Taper Shank Drill 28mm Short Series

Professional 28mm short-series Morse taper shank drill manufactured from HSS-Co8, with Type H geometry, a 130° point angle, special point shape C and STEAMED surface treatment. Designed particularly for manganese steel, high-tensile fine-grained steels such as Hardox® 400/500, and alloyed steels above 1,100 N/mm².

The Maykestag Code 832 is a heavy-duty HSS-Co8 twist drill developed for demanding drilling applications in tough and high-strength steels. Its short-series construction increases rigidity, while the Morse taper shank provides secure mounting in suitable drilling machines and machine-tool spindles. The Type H geometry, 130° point angle and Maykestag special point shape C are designed to support controlled penetration and dependable cutting performance in difficult materials.

Product highlights

• HSS-Co8 construction: Cobalt-alloyed high-speed steel provides excellent hot hardness, toughness and cutting-edge durability for demanding drilling applications.
• 28mm cutting diameter: Precision diameter manufactured to an h8 tolerance.
• Designed for high-strength steels: Developed particularly for manganese steel, Hardox® 400/500 and alloyed steels above 1,100 N/mm².
• Short-series construction: Reduced overall working length increases rigidity and helps minimise deflection under heavy drilling loads.
• Type H geometry: Cutting geometry intended for harder and tougher materials that produce shorter chips.
• 130° point angle: Robust drill-point geometry suited to demanding steel applications.
• Special point shape C: Maykestag's specified special point geometry supports controlled centring and penetration.
• 3 x D drilling depth: Catalogue-rated drilling depth of up to three times the drill diameter under suitable machining conditions.
• STEAMED treatment: Steam-treated surface finish designed to improve surface characteristics and support dependable drilling performance.
• Morse taper No. 4: Precision taper shank for secure mounting in compatible machine spindles or sleeves.
• WN specification: Manufactured according to Maykestag works-standard dimensional and geometry requirements for the Code 832 range.

Designed for Tough and High-Strength Steels

Drilling manganese steel and high-strength fine-grained steels places considerably greater demands on a drill than conventional mild-steel machining. The Code 832 addresses these requirements with a rigid short-series body, heat-resistant HSS-Co8 cutting material and a robust 130° point geometry. On this 28mm model, the 107mm flute length provides the working section while the Morse taper No. 4 shank provides a secure machine connection. Correct cutting speed, feed rate, coolant strategy and machine rigidity remain essential for achieving dependable tool life and accurate holes.
