Built on the CI series platform with a 45-degree lead angle, this cutter handles negative radial and positive axial rake geometries using a 4-insert configuration. The arbor hole diameter is 0.5 inches, and the tool accepts size 08 inserts secured by screw-clamp holding. Coolant-through capability supports chip evacuation and tool life in demanding cuts. The body is machined from steel for rigidity under interrupted and continuous cutting conditions.\u003c\/p\u003e\n\u003cp\u003eThis face mill suits shops performing chamfer preparation, edge breaking, and light face milling on ferrous and non-ferrous workpieces. The right-hand cutting direction and ADSM cutter style make it compatible with standard right-hand spindle setups. With a minimum cutting diameter of 1.5 inches and a maximum cutting diameter of 1.8544 inches, it fits tooling setups where a compact-diameter shell mill arbor is used. The maximum depth of cut is 0.13 inches per pass, positioning this cutter for finishing and semi-finishing chamfer work rather than heavy roughing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree lead angle for consistent chamfer geometry on part edges\u003c\/li\u003e\n  \u003cli\u003e4-insert capacity with screw-clamp holding for repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip removal and extends insert life\u003c\/li\u003e\n  \u003cli\u003eNegative radial and positive axial rake reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003e0.5-inch arbor hole with 0.2657-inch keyway width for positive drive engagement\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body provides stiffness for chatter-free chamfering cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible inserts are HNKU 4.542AZER and HOKU 4.542AZER, size code 08.

Power down and lock out the machine spindle before mounting or removing the cutter body or indexing inserts. Torque the insert screws and arbor retention hardware according to the toolholder manufacturer specifications using calibrated tooling — do not substitute generic fastener torque values. Verify runout with a dial indicator after mounting and before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Cutting Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 1.8544 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1.496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 0.2657 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Inserts\u003c\/strong\u003e: HNKU 4.542AZER, HOKU 4.542AZER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: ADSM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (Radial), Positive (Axial)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.47 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40280216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727814066482,"sku":"40280216","price":470.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c15cd4ba8a11f6aaab7c72b1f506f0f5.jpg?v=1788682871","url":"https:\/\/voomisupply.com\/products\/accupro-40280216-indexable-chamfer-angle-face-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
