The APGT1604PDFR-G2 H01 is a top-tier carbide insert optimised for milling non-ferrous alloys such as aluminium and copper. Manufactured with Mitsubishi’s HTi10 grade, this insert features a bright, uncoated carbide substrate that retains sharp cutting edges and offers excellent wear resistance in aluminium environments. The APGT geometry, combined with a positive rake and lead angle (~11°) delivers smooth chip flow and lowers cutting forces, which reduces vibration and improves the surface finish.

Because it’s uncoated, you avoid issues like built-up edge which are common in coated tools when machining soft, sticky alloys. This means longer intervals between insert changes, less downtime, lower tooling costs overall. Tailored for industries like automotive, aerospace, die & mold and general engineering, the APGT1604PDFR-G2 H01 is ideal for roughing to semi-finishing operations where you need brightness, precision and consistent performance.

Key Features

Key Features & Specs

  • Geometry: APGT-type, positive rake, “PDFR” style — engineered for excellent chip evacuation in rotating tools. Relief angles designed for minimal drag. AN (lead angle) ~11°, IC approx .177” (metric ~4.5-5 mm) per Mitsubishi specs.

  • Grade / Substrate: HTi10 – a hard, uncoated grade formulated for non-ferrous, aluminium and similar materials; offers excellent balance between hardness & toughness without needing coatings. 

  • Coating / Finish: Uncoated (bright carbide / natural finish) to maintain sharp cutting edges & avoid built-up edge when machining aluminium/alloys.

  • Applications: Best suited for milling / rotating tools / face milling / rough-to-semi finishing on aluminium, copper, non-ferrous metals & alloys. Less ideal for hardened steel, but performs well when chip control and smooth surface are critical.

Why It’s a Best Seller

Why It’s a Best Seller

  • Less downtime: because HTi10 and the sharp positive geometry give clean cuts in non-ferrous materials, reducing chip jams, edge build-up and frequent insert changes.

  • Superior surface finish: especially on aluminium alloys – bright finishes, fine tolerances with minimal burrs.

  • High wear resistance: despite being uncoated, HTi10’s microstructure is optimized for non-ferrous work, so edge degradation happens slower in typical feed & speed ranges.

Application

Industries / Applications

  • Automotive: lightweight aluminum parts, housings, engine components

  • Aerospace: non-ferrous structural parts, fixtures

  • Die & Mold: finishing inserts on aluminium molds, pattern blocks

  • General Engineering / OEMs: machining aluminium frames, casings, assemblies

Frequently Asked Questions

It excels in non-ferrous metals (especially aluminium and alloys), copper, and similar soft metals. The uncoated HTi10 grade helps avoid built up edge and ensures clean cuts. Less suited for hardened steels or highly abrasive cast irons.

In aluminium machining, coatings often lead to built-up edge or sticking. HTi10’s uncoated, highly polished carbide surface offers sharper edges and better chip flow, so you often get longer life and better finish, especially at high speeds common with non-ferrous milling.

APGT1604 implies IC (inscribed circle) approx .177 in (~4.5-5 mm), lead angle ~11°, and relief features as per Mitsubishi’s rotating tools catalog.

For aluminium & non-ferrous alloys, high cutting speeds are possible (thanks to low hardness & the HTi10 grade). Feed rates and DOC (depth of cut) will depend on the machine & setup, but you’ll get best results when matched with sharp tools, stable fixturing, and high spindle speeds. (Exact values depend on machine and alloy.)

  • Fewer tool changes → less downtime

  • Better surface finish → less secondary finishing required

  • Higher production rate possible with stable machining due to positive geometry & chip control
    All these add up to lower cost per part / component.
