Seco's new Jabro-Solid2 JS750 end millsClick image to enlarge

Seco Tools has introduced the Jabro-Solid2 JS750 end mills.

Seco says the new end mills can extend tool life by 25 to 40 per cent.

Designed specifically for the aerospace sector, the new JS754 and JS755 tools provide cost-effective high performance to tackle that industry’s challenging materials, including ISO M (stainless steel) and S (heat-resistant superalloys and titanium).

The JS754 and JS755 cutter geometries optimize conventional side milling, roughing and slotting, as well as advanced roughing and dynamic milling operations. Instead of struggling with chip formation, the smooth peripheral rake faces and strong radius design of these cutters evacuate chips efficiently while maintaining a true radius form. To avoid slow or unreliable cutting when interpolating or ramping for pocket machining, increased front back tapers enhance speed and reliability.

The broad range of JS754 and JS755 variations and features allows for superior cutting performance. Shops can match tool to application with various lengths, OD neck reduction sizes and corner radii, as well as chip splitters and through-coolant options.

Range overview (all dimensions metric):

JS754: 4-flute side roughing, side finishing and slotting, APMXS=2*DC +OD:

  • ø3-25 chamfer and radii offer RE0.2 0.5 1.0 1.5 2.0 3.0 4.0 6.0, normal length
  • ø6-20 chamfer ICC through coolant, normal length
  • ø10 and ø12 chamfer including chip splitters, normal length

JS754: 4-flute side roughing, side finishing, APMXS=3.5 – 4*DC + OD:

  • ø6-25 chamfer and radii offer RE0.2 0.5 1.0 2.0 3.0 4.0 6.0, long length
  • ø10-20 chamfer including chip splitters, long length (advanced roughing)

JS755: 5-flute high volume side rough and side finishing, APMXS=2*DC +OD:

  • ø6-25 chamfer and radii offer RE0.5 1.0 2.0 3.0 6.0, normal length

JS755: 5-flute high volume side roughing, side finishing, APMXS=3.5 - 4*DC + OD:
