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 M40x1.5 tap has a reduced shank according to DIN 374: diameter 32 mm, square size 24 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 M40x1.5 thread.
M40x1.5 metric fine machine tap – Fra HSSE for heavy-duty hydraulics
The M40x1.5 metric fine machine tap from Fra is a specialized tool for cutting internal threads with a large diameter of 40 mm in heavy-duty and industrial hydraulic components. Made from HSSE high-speed steel with 5% added cobalt, it guarantees a hardness of 65-67 HRC and optimal tool life when machining difficult-to-machine materials. The M40x1.5 metric fine thread is standard in large-diameter, high-pressure hydraulic connections, providing excellent leak tightness at operating pressures up to 500 bar.
Key advantages of the M40x1.5 Fra machine tap
- Manufacturer Fra as a specialist in special taps, guarantees high manufacturing quality and accurate geometry for large-diameter metric fine threads
- Fine thread with a 1.5 mm pitch is standard in heavy-duty hydraulics, providing excellent leak tightness at high pressures and high flow rates
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, essential for machining alloy steels
- The 6H tolerance in accordance with DIN 374 ensures thread accuracy and full interchangeability with hydraulic fittings
- Compatibility with ER40 holders and collets for precise clamping on CNC machining centers
- The recommended hole diameter of 38.5 mm for the M40x1.5 metric fine thread ensures an optimal percentage of thread engagement
The Fra M40x1.5 machine tap is used in the production of high-power hydraulic cylinders, hydraulic presses, and construction and mining machinery. The metric fine thread provides better sealing than a coarse thread at high pressures. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.
