MAYKESTAG HSS-Co5 Machine Tap M22 x 2.5 Straight Fluted DIN 376 Code 4803

Maykestag HSS-Co5 Machine Tap M22 x 2.5 Straight Fluted

Professional M22 x 2.5 metric machine tap manufactured from HSS-Co5, featuring straight flutes, a Form B chamfer and ISO 2 (6H) thread tolerance. Designed for accurate, reliable production of metric ISO threads in through holes across a versatile range of engineering materials.

The Maykestag Code 4803 M22 machine tap is a precision threading tool for producing M22 x 2.5 metric ISO internal threads in through-hole applications. Its straight-fluted geometry provides a strong and dependable cutting form, while the Form B chamfer of 3.5–5 pitches introduces the cutting load gradually across several teeth for controlled thread generation.

Manufactured from HSS-Co5 cobalt-alloyed high-speed steel, the tap combines toughness with improved resistance to heat and cutting-edge wear. The M22 version follows DIN 376 dimensional requirements and is designed to produce an internal thread to the widely used ISO 2 (6H) tolerance class.

Product highlights

• M22 x 2.5 metric thread: Produces an M22 metric ISO internal thread with a 2.5mm pitch.
• HSS-Co5 construction: Cobalt-alloyed high-speed steel provides an excellent balance of toughness, heat resistance and wear resistance.
• Straight-fluted geometry: Strong and proven cutting design for dependable professional machine tapping.
• Form B chamfer: 3.5–5 pitch lead provides gradual cutting engagement and is especially suited to through-hole tapping.
• ISO 2 (6H) tolerance: Produces a standard general-purpose metric internal thread tolerance widely used in engineering.
• DIN 376: Manufactured to the dimensional standard applicable to this larger machine-tap size.
• Through-hole application: Intended for tapping holes that continue completely through the workpiece.
• 19.5mm tap drill: Maykestag specifies a 19.5mm pre-drilled hole for this M22 x 2.5 tap.
• Green ring classification: Quickly identifies the tool as part of Maykestag&s versatile universal application range.

Designed for Reliable M22 Thread Production

This M22 version features a 2.5mm thread pitch, 140mm overall length and 32mm thread length. Its 18mm shank and 14.5mm square provide a substantial drive section for compatible machine-tapping equipment, while Maykestag specifies a 19.5mm tap-drill diameter. Accurate hole preparation, correct tool alignment, suitable cutting lubricant and the appropriate machining parameters all help reduce tapping torque and promote clean, consistent thread formation.
