Tungaloy introduces CeramicSpeedMill for efficient milling of heat-resistant superalloys (HRSAs).
CeramicSpeedMill offers round ceramic inserts for milling HRSAs efficiently at elevated feeds and speeds. The negative, economical double-sided ceramic inserts offer superior cutting edge integrity. In addition, the new TS200 and TS300 of SiAlON ceramics grades combined with the close-pitch cutter design enables milling of nickel-base superalloys at cutting speeds of over 500 meters per minute (1,640 sfm) and greater feed rates for efficient milling of HRSAs commonly used for aerospace components.
Two standard ceramic grades are available: TS200 is a universal grade for finishing, while TS300 is designed for descaling and other roughing applications. The cutter body is offered in a bore (shell mill) style in diameters of 63 mm and 80 mm, and 2.5" and 3.0" for the inch market.

Ceramic facemill with round ceramic inserts designed for machining heat-resistant superalloys
New SiAlON ceramic grade inserts provide wear and fracture resistance when machining at high feeds and speeds
Cutting tool materials based on aluminum oxide and silicon nitride. Ceramic tools can withstand higher cutting speeds than cemented carbide tools when machining hardened steels, cast irons and high-temperature alloys.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
AddInternalCut inserts are available in two sizes: TCIG10 insert is for internal grooving of minimum bore diameter of 10.5 millimeters (.413 inches) and up. TCIG12 allows a maximum groove depth (CDX) of 3.0 millimeters (.118 inches).
Together with successful AH7025 grade for first choice, AH6235 and AH8005 grades will enhance TungCut performances in parting and grooving operations with interruptions, as well as grooving and turning operations with aggressive conditions.
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…
SDM chipbreaker features unique T-land with variable widths and optimized rake angle that provide the insert with resistance against notch wear. Difficult metals like HRSAs are prone to cause notch wear on the insert cutting edge that can severely deteriorate insert tool life. A combination of SDM…
The series is now introducing TCS18 and TCL18 inserts designed for left-hand cuts, expanding the product lines that, up to now, has offered right-hand inserts only. Grooving and parting tools commonly used in most of the operations performed in conventional CNC lathes and Swiss machines are right-…
BallFinishNose is an effective tool in finishing and semi-finishing, particularly on geometric surfaces and complex 3D contours common to die-mold or aerospace applications. The insert features a unique asymmetric shape. This design allows users to use the same side of the insert always facing the…
DrillMeister drill sleeves are available in 16, 25, and 32 millimeters in diameters for metric sizes and 3/4 inches and one inch for imperial sizes that fit the drill holders of the same sizes equipped in Swiss lathes. All drill sleeves have a threaded connecting port on the sleeve end for easy…
The DMH drill head features a fracture resistant design that is suitable for applications that involve drilling holes through thin-walled sections of workpieces. In normal circumstances, thin walls tend to spring back on the drill after the drill pierces through and exits the hole. In the process,…
Tungaloy has expanded its economical, double-sided negative insert line with the -28 chipbreaker. Featuring a pressed-in chipbreaker geometry with a large inclination angle on the sharp cutting edge, the -28 generates free cutting action with superior chip control. In addition, a negative insert…
FixRMill uses round inserts for machining dies and molds, especially complex male-female main parts such as cavities and projections. The round inserts feature anti-rotation notches on the insert clearance side and matching locations on the pocket seats. These notches not only prevent the insert…
