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 M12x1.5 tap has a reduced shank according to DIN 374: diameter 9 mm, square size 7 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 M12x1.5 thread.
M12x1.5 fine-thread machine tap – Fra HSSE for hydraulics
Manufacturer Fra offers the M12x1.5 fine-thread machine tap made from HSSE high-speed steel with 5% cobalt for industrial hydraulic and pneumatic applications. The M12x1.5 metric fine thread has one of the most popular pitches for the M12 diameter and is widely used in hydraulics, pneumatics, and precision engineering requiring leak-tight connections. As a specialist in fine-thread taps, Fra guarantees the highest manufacturing quality and accurate tool geometry. The tool is intended for professional toolrooms and hydraulic equipment manufacturers requiring high precision.
Advantages and applications of the Fra M12x1.5 machine tap
- Manufacturer Fra as a specialist in special and metric fine thread taps, guarantees high manufacturing quality, precise thread geometry and consistent tool parameters
- Fine thread with a 1.5 mm pitch is standard in industrial hydraulics, providing good connection sealing and higher strength than the M12x1.75 coarse thread
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, extending cutting edge life under intensive use
- Tolerance 6H according to DIN 374 ensures precise thread production and full interchangeability with hydraulic fittings used in industry
- Material versatility covering structural steels up to 800 MPa, alloy steels, austenitic stainless steels 304/316, and gray and ductile cast iron
- The recommended tap drill diameter of 10.5 mm for the M12x1.5 metric fine thread ensures optimal thread engagement with minimal tool load
The Fra M12x1.5 machine tap is used in industrial hydraulics, pneumatics, valve blocks, and precision engineering requiring leak-tight threaded connections. The M12x1.5 thread offers a balance between the leak-tightness of a metric fine thread and assembly speed. Cooling with an oil emulsion at a concentration of 6-8% is recommended to maintain optimum tool life.
