Maykestag HSS-Co5 Machine Tap M2 Straight Fluted ALUNIT
Professional M2 straight-fluted machine tap manufactured from HSS-Co5 for metric ISO threads to DIN 13, featuring a 0.40mm pitch, ISO 2 (6H) tolerance, Form B chamfer and Maykestag ALUNIT® coating for dependable machine threading.
The Maykestag Code 4807 is a precision machine tap designed for producing metric ISO internal threads in through holes. This M2 version cuts a standard M2 x 0.40 thread and combines straight-fluted geometry with a Form B chamfer of 3.5-5 pitches. The tap is manufactured from cobalt-alloyed HSS-Co5 and carries Maykestag’s green-ring Uni classification, identifying it as a versatile tapping tool for a broad selection of suitable engineering materials.
Product highlights

Why Choose Maykestag?
Maykestag is an Austrian cutting-tool manufacturer with a strong focus on precision geometry, reliable dimensional control and clearly defined material applications. These qualities are particularly important in tapping, where thread accuracy depends on the correct combination of tap geometry, thread tolerance, cutting material and machining conditions.
The Code 4807 series combines HSS-Co5, straight-fluted geometry, a Form B chamfer and ALUNIT® coating with Maykestag’s Uni application classification. The result is a professional machine tap developed for repeatable metric ISO thread production across a useful range of workshop and production materials.
Designed for Reliable Metric Threading
This M2 tap is designed around the standard 0.40mm metric coarse pitch and a 60° ISO thread profile. The Form B lead distributes the cutting action over approximately 3.5-5 pitches, helping the tap enter the prepared hole progressively. For this M2 size, Maykestag specifies a 1.6mm tapping drill diameter, an overall length of 45mm and a thread length of 8mm. Correct alignment, suitable lubrication and the appropriate cutting data are important for achieving accurate threads and dependable tool life.
