Product description
Maykestag HSS-Co5 Machine Tap M30 x 3.5 Straight Fluted
Professional M30 x 3.5 metric machine tap manufactured from HSS-Co5, featuring straight flutes, a Form B chamfer and ISO 2 (6H) thread tolerance. Designed for dependable production of large metric ISO threads in through holes, with Maykestag's green-ring universal classification for a broad range of engineering materials.
The Maykestag Code 4803 M30 machine tap is a precision threading tool for producing M30 x 3.5 metric ISO internal threads in through-hole applications. Its straight-fluted geometry provides a strong and proven cutting form, while the Form B chamfer of 3.5–5 pitches distributes the cutting action progressively across several teeth for controlled thread generation.
Manufactured from HSS-Co5 cobalt-alloyed high-speed steel, this substantial M30 tap combines the toughness required for high tapping torque with improved heat resistance and cutting-edge durability. The M30 version is manufactured to DIN 376 dimensions and is designed to produce a metric internal thread to the widely used ISO 2 (6H) tolerance class.
Product highlights
- M30 x 3.5 metric thread: Produces a large M30 metric ISO internal thread with a 3.5mm pitch.
- HSS-Co5 construction: Cobalt-alloyed high-speed steel offers an excellent combination of toughness, heat resistance and cutting-edge durability.
- Straight-fluted geometry: Robust and proven cutting design for dependable professional machine tapping.
- Form B chamfer: 3.5–5 pitch lead progressively introduces the cutting load and is particularly suited to through-hole tapping.
- ISO 2 (6H) tolerance: Produces a standard general-purpose metric internal thread tolerance widely used in mechanical engineering.
- DIN 376: Manufactured to the dimensional standard applicable to this larger machine-tap size.
- Through-hole application: Designed specifically for holes that continue completely through the workpiece.
- 26.5mm tap drill: Maykestag specifies a 26.5mm pre-drilled hole for this M30 x 3.5 tap.
- Green ring classification: Identifies the Code 4803 as part of Maykestag's universal application range.
Why Choose Maykestag?
Maykestag is an Austrian cutting-tool specialist focused on precision-manufactured tooling for professional machining. With a large thread such as M30, correct tool geometry, dimensional accuracy and material quality become particularly important because the tap must withstand substantial cutting forces while producing a consistent thread profile throughout the hole.
The Code 4803 series combines HSS-Co5 tool material with straight-fluted geometry, a Form B chamfer and ISO 2 (6H) thread accuracy. The result is a practical professional threading tool for engineering workshops, maintenance operations and production environments where reliable, repeatable metric threads are required.
Designed for Reliable M30 Thread Production
This M30 version has a 3.5mm thread pitch, 180mm overall length and 40mm thread length. The substantial 22mm shank and 18mm square provide a strong drive section for compatible machine-tapping equipment, while Maykestag specifies a 26.5mm tap-drill diameter for correct hole preparation. With a tap of this size, rigid alignment, the correct cutting speed, suitable lubrication and accurate pre-drilling are especially important for managing tapping torque and achieving clean, consistent threads.

Extra Info
Green ring classification
The green ring on this Maykestag Code 4803 machine tap is a quick visual identifier for its universal application classification. The colour coding helps operators identify the intended tool family at a glance, especially where several Maykestag taps for different material groups are kept together.
For the Code 4803 series, the green-ring classification identifies a versatile machine tap with rated capability across several common engineering materials. Maykestag gives the series its highest rating in steels below 400 N/mm², while also rating it for higher-strength steels, stainless steels, cast iron, copper and brass, aluminium and plastics.
Important: The green ring is an application-classification marking and should not be confused with a surface coating. It identifies the intended application range of the tool rather than describing a cutting-surface treatment.
