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 M48x1.5 tap has a reduced shank according to DIN 374: diameter 36 mm, square size 29 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 M48x1.5 thread.
M48x1.5 metric fine machine tap – HSSE for extreme-duty hydraulics
The M48x1.5 metric fine thread machine tap is a specialized tool for cutting internal threads with a very large diameter of 48 mm in components for extreme-duty hydraulics and heavy industry. HSSE high-speed steel with 5% cobalt ensures a hardness of 65-67 HRC and optimum tool life when machining difficult-to-machine materials. The M48x1.5 metric fine thread is a standard in high-pressure hydraulic connections of the largest diameters, providing excellent sealing at operating pressures up to 500 bar.
Key advantages of the M48x1.5 metric fine thread machine tap
- Very large M48 diameter used in heavy industry, construction and mining machinery, and high-power hydraulic cylinders
- Fine thread with a 1.5 mm pitch is a standard in extreme-duty hydraulics, providing excellent sealing at high pressures and very 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 specialized holders for large-diameter threads on CNC machining centers
- The recommended hole diameter of 46.5 mm for the M48x1.5 metric fine thread ensures an optimal percentage of thread engagement
The M48x1.5 machine tap is used in the production of hydraulic cylinders with the highest power ratings, hydraulic presses, and construction and mining machinery. The metric fine thread provides better sealing than a coarse thread at extreme pressures. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.
