Maykestag HSS-Co5 Machine Tap M24 x 3 Straight Fluted DIN 376 Code 4803

Product information

Maykestag HSS-Co5 Machine Tap M24 x 3 Straight Fluted Professional M24 x 3 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 M24 machine tap is a precision threading tool for producing M24 x 3 metric ISO internal threads in through-hole applications. Its straight-fluted geometry provides a strong, dependable cutting form, while the Form B chamfer of 3.5–5 pitches introduces the cutting load progressively across several cutting teeth for controlled and consistent thread generation. Manufactured from HSS-Co5 cobalt-alloyed high-speed steel , this tap offers the toughness needed to withstand the significant torque involved in larger-diameter tapping, together with improved resistance to heat and cutting-edge wear. The M24 version is manufactured to DIN 376 dimensional requirements and produces an internal thread to the widely used ISO 2 (6H) tolerance class. What is a straight-fluted machine tap? A straight-fluted machine tap has flutes running parallel with the centreline of the tool. This creates a robust cutting geometry with strong cutting teeth and generous flute space. Combined with the Code 4803's Form B chamfer, this design is particularly well suited to machine tapping through holes where the cutting section can continue beyond the underside of the workpiece. Product highlights • M24 x 3 metric thread: Produces an M24 metric ISO internal thread with a 3mm pitch. • HSS-Co5 construction: Cobalt-alloyed high-speed steel provides an excellent combination of toughness, heat resistance and wear resistance. • Straight-fluted geometry: Strong, proven cutting design for dependable professional machine tapping. • Form B chamfer: 3.5–5 pitch lead provides gradual cutting engagement and is particularly 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: Designed for holes that continue completely through the workpiece. • 21mm tap drill: Maykestag specifies a 21mm pre-drilled hole for this M24 x 3 tap. • Green ring classification: Quickly identifies the tool as part of Maykestag's versatile universal application range. Why Choose Maykestag? Maykestag is an Austrian cutting-tool specialist focused on precision-manufactured tooling for professional machining. Accurate thread production depends on much more than nominal thread size: tool geometry, material quality, dimensional tolerances and correct machining conditions all influence cutting torque, thread accuracy, surface quality and tool life. The Code 4803 series combines durable HSS-Co5 construction with straight-fluted geometry, a Form B chamfer and ISO 2 (6H) thread accuracy. This makes it a dependable choice for engineering workshops, maintenance departments and production environments where repeatable, accurately formed metric threads are essential. Designed for Reliable M24 Thread Production This M24 version features a 3mm thread pitch , 160mm overall length and 36mm thread length . Its substantial 18mm shank and 14.5mm square provide a positive drive connection for compatible machine-tapping equipment. Maykestag specifies a 21mm tap-drill diameter for correct hole preparation. Using the correct hole size, accurate tool alignment, suitable cutting lubricant and appropriate cutting parameters helps control tapping torque while supporting clean thread formation and dependable tool life.
