Replaceable Carbide-Insert Square End Mill Holders for Manual Milling Machines


Square Cut Style	End Mill Body Shown with Inserts (Sold Separately)

Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire tool. End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

R8 Taper Shank—R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.

Cobalt Steel Square End Mills

With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. They have a square end for milling square slots, pockets, and edges.

End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.

Uncoated Cobalt Steel—Use uncoated end mills for general purpose milling and short production runs.

Titanium Carbon Nitride (TiCN)-Coated Cobalt Steel—Use titanium carbon nitride (TiCN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum.

Center Cutting—Center-cutting end mills allow plunge cuts into a surface.

Noncenter Cutting—Noncenter-cutting end mills are for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.
