The uncoated (bright) body provides clear visibility for wear and chip clearance. Adjustment is achieved by a fine pitch screw that forces the sides apart or allows them to spring together. Chamfering is on both faces: one side uses a two-to-three thread chamfer for threading, the other side uses a one-to-one-and-a-half thread chamfer for threading close to a shoulder. The beveled slot accommodates use in a machine holder, and the adjusting screw can be removed to allow adjustment via the holder’s screws.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eThread size: #12-28\u003c\/li\u003e \u003cli\u003eHandedness: Left-hand thread\u003c\/li\u003e \u003cli\u003eOuter diameter: 1 inch\u003c\/li\u003e \u003cli\u003eMaterial: High Speed Steel (HSS)\u003c\/li\u003e \u003cli\u003eFinish: Uncoated (Bright)\u003c\/li\u003e \u003cli\u003eAdjustment mechanism: Fine pitch screw to separate or bring sides together\u003c\/li\u003e \u003cli\u003eChamfer geometry: one end two-to-three thread chamfer; other end one-to-one-and-a-half thread chamfer\u003c\/li\u003e \u003cli\u003eType: Round adjustable die, chamfered on both faces\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eHigh Speed Steel construction for improved wear life in threading applications\u003c\/li\u003e \u003cli\u003eLeft-hand threading capability for dedicated left-handed fasteners\u003c\/li\u003e \u003cli\u003eDual-face chamfer geometry supports starting and finishing threads in tight spaces\u003c\/li\u003e \u003cli\u003eFine pitch adjustment screw provides precise control over die opening\u003c\/li\u003e \u003cli\u003eBeveled slot design enables adjustment in a machine holder; the adjusting screw can be removed to use holder screws for adjustment\u003c\/li\u003e \u003cli\u003eClear, bright finish aids inspection of chip clearance and wear\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003ePhysical\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eShape: Round die\u003c\/li\u003e \u003cli\u003eFinish: Uncoated (Bright)\u003c\/li\u003e \u003cli\u003eDiameter specification: 1 inch outer diameter\u003c\/li\u003e \u003cli\u003eThread capability: #12-28 with left-hand orientation\u003c\/li\u003e \u003cli\u003eChamfer specifics: two-to-three thread chamfer on one face; one-to-one-and-a-half thread chamfer on the opposite face\u003c\/li\u003e \u003cli\u003eSlot: Beveled to allow adjustment via machine holder screws after removing the adjusting screw\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Drill America","offers":[{"title":"Default Title","offer_id":52459774509335,"sku":"DWTH1-1228LH","price":19.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/1125\/5063\/files\/NPS_HSS_Round_Dies.jpg?v=1773676274","url":"https:\/\/mutualscrew.com\/products\/hss-left-hand-round-adjustable-die-12-28-1-od-uncoated-bright-inch_dwth1-1228lh","provider":"Mutual Screw \u0026 Supply","version":"1.0","type":"link"}
