Endmills

Endmills tipped with CBN, which is the second hardest material after diamond, are offered in sizes ranging from 6mm down to 0.1mm in diameter, with various configurations, from sharp corner, radius corner, ball, standard neck length and extended neck length. TOWA offers their CBN endmills in multi-flute configurations. By maintaining the same feed per flute, and increasing the number of flutes, cutting time is reduced, while profitability is increased. The CBN series of endmills, due to the hardness of the CBN, is an excellent choice for machining harden materials in the range of 55 to over 60 Rockwell “C”.

The A Brand AE-VTSS end mill offers the following features & benefits: Positive rake angle which reduces cutting force. High rigidity to improve milling accuracy. New flute form that facilitates excellent chip evacuation. Duarise coating to minimize thermal cracks. Variable leads which enables stable and high efficiency milling.

The A Brand AE-CR-MS-H end mill offers the following features & benefits: Variable index to reduce chattering. Cutting edge geometry for stable machining of high-hardness steels. DUROREY coating which allows for outstanding performance in high-hardness steels

The PHOENIX PXM-PXSH end mill offers the following features & benefits: OSG's proven cutting geometries and coatings produces high performance in a variety of applications and materials. 2-face contact (end face and taper) and buttress thread for fast and highly rigid clamping. Radial runout less than 15µm and axial repeatability ±30µm for high accuracy and repeatability. End mill style, inch and metric provides a complete offering.

The 5-flute square-end end mill with sharp edges, chamfers and corner radii joins a 4-flute square-end and ball-nose end mill with both straight and Weldon® shanks as part of WIDIA’s WCE solid end mill portfolio. The WCE4, a 4-flute geometry solid end mill, combines the asymmetrical index and variable helix features to excel in operations like full slots and heavy cuts. 

SolidMeister barrel endmills are efficient tools for complex 3D surfacing operations used in mold making, orthopedic implant work, and the machining of gas turbine blades and other freeform surfaces in the aerospace and energy industries. The endmills incorporate a cutting edge that is actually the segment of a large-diameter arc. Since the shape of the cutting edge resembles a barrel profile, the tool became known as barrel endmills, or in shop talk, simply as barrels.

Beyond shoulder and face milling, the end mills can also be used for pocket milling, helical interpolation, ramping and slot milling. The CoroMill 316 is part of the Sandvik Coromant Optimized Solutions offering in the company’s solid round tools range.

What makes the CoroMill Dura stand out compared to the former versatile concept and competitor end mills is its WhisperKut technology. The CoroMill Dura is available from two to seven flutes with 1-4×D cutting length, with and without a chip divider. The end mills can be reconditioned up to three times to original specifications.
