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 M60x3 tap has a reduced shank according to DIN 374: diameter 45 mm, square size 35 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 3 mm/rev, equal to the pitch of the M60x3 thread.
M60x3 metric fine thread machine tap – Fra HSSE for extreme-duty structures
The Fra M60x3 metric fine thread machine tap is a specialized tool for cutting internal threads with an extremely large diameter of 60 mm in components for heavy industry and the power industry. HSSE high-speed steel construction with 5% added cobalt guarantees a hardness of 65-67 HRC and optimal tool life when machining difficult-to-machine materials. As a specialist in special-purpose taps, Fra guarantees the highest quality when cutting large threads.
Why choose the Fra M60x3 machine tap
- Manufacturer Fra as a specialist in special-purpose taps, guarantees high manufacturing quality and accurate geometry for threads of extremely large diameter
- Fine thread with a 3 mm pitch offers significantly higher tensile strength than the M60x5.5 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
- The 6H tolerance in accordance with DIN 374 ensures thread accuracy and full interchangeability with fasteners
- Compatibility with ER40 holders and specialized chucks for threads of extremely large diameter
- The recommended hole diameter of 57 mm for the M60x3 metric fine thread ensures an optimal percentage of thread engagement
The Fra M60x3 machine tap is used in the power industry, turbine and mining machinery construction, and steel structures of extreme dimensions. The metric fine thread provides higher strength than a coarse thread while maintaining relatively quick assembly. Cooling with an emulsion containing EP additives at a concentration of 8-10% is recommended.
