Manufactured from \u003cstrong data-start=\"189\" data-end=\"207\"\u003ehardened steel\u003c\/strong\u003e, this drill bit is engineered to provide reliable durability and consistent cutting performance in fabrication and machining environments.\u003c\/p\u003e\n\u003cp data-start=\"348\" data-end=\"725\"\u003eThis drill bit features a \u003cstrong data-start=\"374\" data-end=\"417\"\u003e90-degree point angle and 0-degree rake\u003c\/strong\u003e, which helps prevent grabbing and chipping when drilling plastics such as acrylic, polycarbonate, PVC, and other plastic sheet materials commonly used in sign fabrication and plastic processing. The geometry of the bit is designed to produce cleaner holes while reducing stress on brittle plastic materials.\u003c\/p\u003e\n\u003cp data-start=\"727\" data-end=\"1099\"\u003eThe drill bit includes a \u003cstrong data-start=\"752\" data-end=\"777\"\u003estraight shank design\u003c\/strong\u003e, allowing compatibility with most standard drill chucks and drill presses used in fabrication shops and machining environments. On larger bit sizes such as \u003cstrong data-start=\"934\" data-end=\"952\"\u003e7\/16\" and 1\/2\"\u003c\/strong\u003e, the shank is reduced to \u003cstrong data-start=\"978\" data-end=\"986\"\u003e3\/8\"\u003c\/strong\u003e to maintain compatibility with standard tooling, while smaller sizes maintain a shank equal to the bit diameter.\u003c\/p\u003e\n\u003cp data-start=\"1101\" data-end=\"1307\"\u003eThis type of drill bit is commonly used in \u003cstrong data-start=\"1144\" data-end=\"1243\"\u003eplastic fabrication, sign production, acrylic drilling, and general shop machining applications\u003c\/strong\u003e where controlled drilling and clean hole finishes are required.\u003c\/p\u003e\n\u003cp data-start=\"1309\" data-end=\"1327\"\u003e\u003cstrong data-start=\"1309\" data-end=\"1327\"\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1329\" data-end=\"1622\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eProduct: Plastic Drill Bit\u003cbr data-start=\"1378\" data-end=\"1381\"\u003eBit Size: .437\" (7\/16\")\u003cbr data-start=\"1404\" data-end=\"1407\"\u003eMaterial: Hardened Steel\u003cbr data-start=\"1431\" data-end=\"1434\" data-is-only-node=\"\"\u003ePoint Angle: 90°\u003cbr data-start=\"1450\" data-end=\"1453\"\u003eRake Angle: 0°\u003cbr data-start=\"1467\" data-end=\"1470\"\u003eShank Type: Straight Shank\u003cbr data-start=\"1496\" data-end=\"1499\"\u003eReduced Shank: 3\/8\" on 7\/16\" and 1\/2\" Sizes\u003cbr data-start=\"1542\" data-end=\"1545\"\u003eApplication: Drilling Plastics, Acrylic, Polycarbonate, PVC, Fabrication Work\u003c\/p\u003e","brand":"SF Plastic \u0026 Sign Supply","offers":[{"title":"Default Title","offer_id":62817475690865,"sku":"1748","price":27.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2628\/6705\/files\/drillbit437hb-4272617.jpg?v=1775159685","url":"https:\/\/sfplasticsignsupply.myshopify.com\/products\/drillbit-437hb","provider":"SFPlasticSignSupply","version":"1.0","type":"link"}
