{"product_id":"p-1683649","title":"Reduced Shank Drill Bit 1\/2\" Shank 4341 High-Speed Steel 118°","description":"1. The 4341 high-speed steel material typically exhibits superior corrosion resistance and higher strength, making it suitable for operation under high-temperature conditions. Its heat resistance allows for the manufacture of cutting tools that require higher performance. Additionally, the nitrided layer provides oxidation and corrosion resistance, thereby extending the tool's lifespan.\u003cbr\u003e\u003cbr\u003e2. 118° Conventional Point, not easy to slide, suitable for wood, plastic soft metal, and other materials drilling, widely used in daily operation, more appropriate for home and light industry use, simple operation, strong adaptability.\u003cbr\u003e\u003cbr\u003e3. Suitable for soft metal and woodworking projects, widely used in daily operations such as home maintenance, suitable for processing medium hardness materials, such as copper, aluminum, iron, plastic, and wood\u003cbr\u003e\u003cbr\u003e4. About the relationship between the bit and the speed, larger bits need lower RPM, smaller bits require higher RPM, and harder materials require lower RPM for better cutting performance and longer drill life.\u003cbr\u003e\u003cbr\u003e5. When using a reduced shank drill bit, it’s crucial to maintain a 90-degree vertical angle for precision and accuracy. Additionally, water or coolant should be used to reduce temperature and prevent overheating. This helps ensure optimal performance and extends the lifespan of the drill bit.","brand":"Harfington","offers":[{"title":"18.5mm","offer_id":46560556056825,"sku":"f24103100ux0314","price":11.42,"currency_code":"USD","in_stock":true},{"title":"17.5mm","offer_id":46560556548345,"sku":"f24103100ux0312","price":10.99,"currency_code":"USD","in_stock":true},{"title":"14.5mm","offer_id":46560556646649,"sku":"f24103100ux0307","price":9.62,"currency_code":"USD","in_stock":true},{"title":"15.5mm","offer_id":46560556679417,"sku":"f24103100ux0309","price":10.01,"currency_code":"USD","in_stock":true},{"title":"19.5mm","offer_id":46560556974329,"sku":"f24103100ux0316","price":11.7,"currency_code":"USD","in_stock":true},{"title":"29.50mm","offer_id":46560556122361,"sku":"f24103100ux0123","price":17.77,"currency_code":"USD","in_stock":true},{"title":"29.5mm","offer_id":46560556155129,"sku":"f24103100ux0101","price":18.18,"currency_code":"USD","in_stock":true},{"title":"20.5mm","offer_id":46560556220665,"sku":"f24103100ux0318","price":11.82,"currency_code":"USD","in_stock":true},{"title":"26.5mm","offer_id":46560556384505,"sku":"f24103100ux0098","price":15.84,"currency_code":"USD","in_stock":true},{"title":"21.5mm","offer_id":46560556482809,"sku":"f24103100ux0320","price":12.3,"currency_code":"USD","in_stock":true},{"title":"28.50mm","offer_id":46560556744953,"sku":"f24103100ux0122","price":18.25,"currency_code":"USD","in_stock":true},{"title":"28.5mm","offer_id":46560556810489,"sku":"f24103100ux0100","price":18.22,"currency_code":"USD","in_stock":true},{"title":"24.5mm","offer_id":46560556843257,"sku":"f24103100ux0326","price":14.28,"currency_code":"USD","in_stock":true},{"title":"26.50mm","offer_id":46560556876025,"sku":"f24103100ux0121","price":15.4,"currency_code":"USD","in_stock":true},{"title":"22.5mm","offer_id":46560557007097,"sku":"f24103100ux0322","price":12.88,"currency_code":"USD","in_stock":true},{"title":"23.5mm","offer_id":46560557072633,"sku":"f24103100ux0324","price":13.36,"currency_code":"USD","in_stock":true},{"title":"14mm","offer_id":46560556318969,"sku":"f24103100ux0306","price":9.51,"currency_code":"USD","in_stock":true},{"title":"15mm","offer_id":46560556908793,"sku":"f24103100ux0308","price":9.78,"currency_code":"USD","in_stock":true},{"title":"16mm","offer_id":46560557039865,"sku":"f24103100ux0310","price":10.22,"currency_code":"USD","in_stock":true},{"title":"18mm","offer_id":46560556286201,"sku":"f24103100ux0313","price":11.2,"currency_code":"USD","in_stock":true},{"title":"19mm","offer_id":46560556417273,"sku":"f24103100ux0315","price":11.14,"currency_code":"USD","in_stock":true},{"title":"20mm","offer_id":46560556351737,"sku":"f24103100ux0317","price":12.48,"currency_code":"USD","in_stock":true},{"title":"21mm","offer_id":46560556253433,"sku":"f24103100ux0319","price":12.0,"currency_code":"USD","in_stock":true},{"title":"22mm","offer_id":46560556089593,"sku":"f24103100ux0321","price":12.55,"currency_code":"USD","in_stock":true},{"title":"23mm","offer_id":46560556187897,"sku":"f24103100ux0323","price":13.22,"currency_code":"USD","in_stock":true},{"title":"24mm","offer_id":46560556712185,"sku":"f24103100ux0325","price":13.94,"currency_code":"USD","in_stock":true},{"title":"25mm","offer_id":46560556613881,"sku":"f24103100ux0096","price":14.51,"currency_code":"USD","in_stock":true},{"title":"26mm","offer_id":46560556450041,"sku":"f24103100ux0097","price":15.04,"currency_code":"USD","in_stock":true},{"title":"27mm","offer_id":46560556515577,"sku":"f24103100ux0099","price":16.88,"currency_code":"USD","in_stock":true},{"title":"30mm","offer_id":46560556941561,"sku":"f24103100ux0102","price":18.55,"currency_code":"USD","in_stock":true},{"title":"32mm","offer_id":46560556777721,"sku":"f24103100ux0103","price":19.68,"currency_code":"USD","in_stock":true},{"title":"35mm","offer_id":46560556581113,"sku":"f24103100ux0104","price":21.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_f24103100ux0314_ux_g03.jpg?v=1749970228","url":"https:\/\/www.harfington.com\/products\/p-1683649","provider":"Harfington","version":"1.0","type":"link"}
