How the type B through-hole chamfer pushes chips down the hole
Chips exit at the bottom instead of returning through the thread
The form B chamfer for through holes has a chip breaker at the tip of the tap – an angled cut in the cutting edges. The chip breaker directs the chip down the hole, ahead of the tap tip. The chip curls into a coil, breaks into short pieces and exits the hole on the other side of the workpiece. The threads already cut remain clean because the chip does not pass through them on its way up. The M22x1.5 tap has a reduced shank according to DIN 374: diameter 18 mm, square size 14.5 mm.
1
Straight flute – chips do not enter it; the flute carries lubricant to the cutting edges.
2
The chip breaker at the tip of the tap directs chips down the hole.
3
The tap rotates clockwise to cut a right-hand thread.
4
B chamfer: 3.5–5.5 incomplete threads on the entry taper.
5
The chips break into segments: individual pieces at the top of the hole, with progressively more farther down. They fall out below the workpiece.
6
Feed 1.5 mm/rev, equal to the pitch of the M22x1.5 thread.
M22x1.5 metric fine thread machine tap – HSSE for hydraulic power systems
The M22x1.5 metric fine thread machine tap is designed for precision tapping of holes in hydraulic power components. HSSE high-speed steel construction with 5% cobalt ensures a hardness of 65-67 HRC and optimal tool life when machining materials with a strength of up to 800 MPa. The M22x1.5 metric fine thread is standard in high-pressure hydraulic connections, providing excellent leak tightness and high joint strength. The 6H tolerance according to DIN 374 ensures the dimensional repeatability required in series production.
Technical specifications of the M22x1.5 metric fine thread machine tap
- Fine thread with a 1.5 mm pitch is standard in hydraulic power systems, providing excellent leak tightness at operating pressures up to 400 bar
- Increased load-bearing area of the thread of the metric fine thread results in more uniform load distribution and greater resistance to pressure pulsations
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, essential for machining alloy steels
- Compliance with DIN 374 confirms manufacturing quality and ensures standardized dimensions for metric fine threads
- Compatibility with ER32 holders and collets for precise clamping on CNC machining centers
- Recommended tap drill diameter 20.5 mm for the M22x1.5 metric fine thread ensures optimal thread engagement
The M22x1.5 metric fine thread machine tap is used in the production of valve blocks, pump bodies, cylinders and high-pressure hydraulic fittings. A metric fine thread provides better sealing than a coarse thread thanks to the greater number of threads per unit length. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.

Frequently asked questions
The M22x1.5 thread is standard in hydraulics due to its excellent leak tightness at high pressures, high joint strength and the wide availability of hydraulic fittings and components in this size.
The recommended tap drill diameter for the M22x1.5 metric fine thread is 20.5 mm. Precise hole machining is essential for leak-tight hydraulic connections.
The M22x1.5 metric fine thread combined with steel connecting components withstands operating pressures up to 400 bar in typical hydraulic applications. Leak tightness depends on seal quality.
