Millstar Products: High Speed and Hardened Metal Machining Carbide Inserts
Millstar inserts are fully ground precision inserts for better chip control, faster metal removal and higher surface accuracies. They are far more accurate than pressed and O.D. sharpened inserts.
- Positive ground chipbreaker or strong negative cutting edge designs for optimal performance with a variety of materials.
- State-of-the-art insert grades, designs and tool coating options for superior speed and feed rates
- Economical one-piece inserts with two cutting edges for cost-effective contour milling
- Side-cutting ball nose inserts with 180° nose radius or popular ball nose inserts with a 230° cutting edge for steep wall up-and-down ramping, profiling, contour milling and blending.
- Variety of flat bottom, back draft and toroid inserts for steep or straight wall milling with long extensions on hard to reach cores, cavities or fillets.
Ball Nose Carbide Inserts
MBT SuperFinisher Ball Nose Insert
Precision ground, harder grade, for semi-finish and finish milling. Excellent choice for unattended finish milling at small depth and high speeds and feed rates.
Unique cutting edge allows performance in all operations in material below 42HRc; in semi and finishing operations above. Significant benefits in heat-treated intricate geometries. Insert geometry allows smoother cutting motion - diminishing heat build up & tool deflection, reduces vibration caused by cutting action.
Used for semi and finish milling small radius or detail work, and surface milling in soft and hard steel, cast iron, aerospace and non-ferrous alloys, graphite, etc. Suitable for high speed and hard milling.
Precision ground, non-chipbreaker. Best choice for cavity, core and profile milling of pre-hard and fully hard die/mold steels, cast steels and cast iron. Strongest cutting edge design.
Precision ground for semi-finish and finish milling. Excellent choice for unattended finish milling at small depth and high speed and feed rates.
Sidecutting, non-chipbreaker. Side cutting insert used in cavity and core pro-filing, for blending of fillets on medium and hard materials.
Flat Bottom Carbide Inserts
Precision ground, non-chipbreaker. Unique crossover design between flat bottom FB and back draft BD inserts. Allows straight walls with a larger step down than BD, but less cutting forces than FB; allows higher cutting speeds and feeds.
Precision ground, with positive ground chipbreaker. Flat bottom insert for shoulder milling, fillet finishing and long reach angular wall finishing of softer materials.
High Feed Carbide Inserts
Millstar's HF insert is designed for high cutting speeds & feed rates with shallow depth of cut. Innovative curved geometry allows chips to flow up and out of the cut quickly & smoothly to accommodate heavy chip loads. HF also directs cutting forces upward toward the spindle to minimize vibration & deflection, allowing for very high chip loads. HF fits Millstar's standard flat holders, style 4 (CYF, TAF and CBCYF), making these hodlers more versatile than ever.
Back Draft Carbide Inserts
Precision ground, with positive ground chipbreaker and 7 degree back-taper. Used for milling of cores, cavities, fillets with straight or very steep walls of softer material.
Used for semi and finish-illing small radius or detail work, and surface milling in soft and hard steel, cast iron, aerospace and non-ferrous alloys, aluminum alloys, graphite, etc. Suitable for high speed and hard milling.
Precision ground, non-chipbreaker and 7 degree backtaper. Used for milling of cores, cavities, fillets with straight or very steep walls of harder material.
TOBD-NF Back Draft Inserts for Non-Ferrous Materials
Millstar's TOBD-NF insert is specifically designed for high speed & high feed roughing of Aluminum, but also has the verstility to perform fine finishing. Unique cutting edge design allows chips to flow freely up the flute, allowing higher speeds & feeds. TOBD-NF comes in diameters from 1/2 inch (12mm) to 1 inch (25mm) and fits into our versatile standard flat type tool holders.
For high speed machining or milling of high hardness materials with longer tool life and superior finishes.
For carbon milling with longer tool life.
Toroid Carbide Inserts
Precision ground, large corner radius & back taper for spiral and pocket milling, milling of pre-hard and hardened flat surfaces at higher speeds than tools with smaller corner radii. Good choice for HS milling of Aluminum.
