Small cylindrical carbide end mill, gold TiAlN coating, 1.80 mm diameter, 4.50 mm cut length

OSG

OSG HP416-0709 Carbide End Mill 1.80mm 4.50mm Cut L

SKU CH-M8X2-ZWZV9

Carbide ball end mill with 1.80 mm diameter and 4.50 mm cut length for precision milling

  • Precise 1.8 mm milling diameter for fine detail work
  • 50 mm cut length enables shallow profiling
  • Carbide construction resists wear in hard materials
  • TiAlN coating reduces friction and heat buildup
  • Non-coolant-through design simplifies tool setup

OSG HP416-0709 Carbide End Mill

The OSG HP416-0709 is a solid carbide ball end mill designed for precision milling operations. Its 1.80 mm cutting diameter suits detailed contouring and finishing tasks in a variety of materials. Machinists and toolmakers select this cutter for high-accuracy profiling work. The TiAlN coating enhances wear resistance and extends tool life during production runs.

Cutting Length and Coolant Constraints

The flute length measures 4.50 mm, which limits the maximum depth of cut in a single pass. This tool is not coolant-through, so external flood or mist coolant must be used for chip evacuation and heat control. Without through-spindle delivery, deep pocketing may require pecking cycles to clear swarf effectively. The coating allows higher cutting speeds but does not remove the need for proper lubrication.

Shank and Holder Compatibility Check

Verify that your tool holder or collet accepts the shank diameter of this specific end mill before ordering. Ensure the machine spindle provides sufficient runout accuracy for a 1.80 mm carbide cutter to prevent premature failure. Confirm the workpiece material and machining strategy match the capabilities of a non-coolant-through, TiAlN-coated ball nose geometry. Orders of $75 or more ship free from the supplier.

Questions about this item

Is the 1.80 mm diameter the right choice for my finishing passes?

The 1.80 mm diameter suits light finishing work in steel and hardened alloys; the 4.50 mm cut length limits depth of cut to shallow profiles.

What does the TiAlN coating actually do during cutting?

The TiAlN coating raises surface hardness and heat resistance, letting the tool run at higher speeds while reducing built-up edge on stainless and tool steels.

Does the non-coolant-through design limit the materials I can machine?

Without internal coolant you rely on flood or mist for chip evacuation; this works well for shallow slots in steel but may struggle in deep pockets or sticky alloys.
