{"product_id":"p-1367211","title":"Nitride Coated High Speed Steel Reduced Shank Drill Bit for Metal Drilling","description":"\u003cstrong\u003eApplications \u0026amp; Features:\u003c\/strong\u003e\u003cbr\u003e--- Widely used for drilling stainless steel, aluminum alloy, cast iron, high carbon steel, copper, hard wood, hard plastic, and other metal materials in maintenance departments, machine shops, and other industries. Reduced shank drill bits expand the size range capacity of portable drill chucks. Use on drill presses and bench drills. The appropriate lubricant is beneficial for cutting or cooling, improving dimensional accuracy and extending tool life.\u003cbr\u003e--- The twist drill bit is made of high-speed steel, with high hardness, good toughness, high strength. The nitride coating has excellent wear resistance, corrosion resistance and high temperature resistance. Provides better lubricant application, smoother drilling, and is more durable and corrosion resistant than regular silver tone surfaces. Sharp spiral flutes provide fast, neat and smooth cuts. The spiral groove facilitates the export of metal chips, which saves time and effort in operation. Designed with small pockets to keep coolant near the cutting edge.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUseful Tips:\u003c\/strong\u003e\u003cbr\u003e--- Drilling edges with burrs: Reduce the number of holes drilled and check various cutting conditions to ensure proper tool handling. Reduce forward and reverse speed. Use harder aluminum and wood. Drill metal with high hardness, the rotational speed should be slower than normal drilling.","brand":"Harfington","offers":[{"title":"16.5mm","offer_id":46800703881465,"sku":"f22110400ux0222","price":14.56,"currency_code":"CAD","in_stock":true},{"title":"19.5mm","offer_id":46800703914233,"sku":"f22110400ux0313","price":16.07,"currency_code":"CAD","in_stock":true},{"title":"18.5mm","offer_id":46800703979769,"sku":"f22110400ux0307","price":19.2,"currency_code":"CAD","in_stock":true},{"title":"14.5mm","offer_id":46800704045305,"sku":"f22110400ux0234","price":14.6,"currency_code":"CAD","in_stock":true},{"title":"13.5mm","offer_id":46800704110841,"sku":"f22110400ux0288","price":14.47,"currency_code":"CAD","in_stock":true},{"title":"17.5mm","offer_id":46800704241913,"sku":"f22110400ux0290","price":16.02,"currency_code":"CAD","in_stock":true},{"title":"15.5mm","offer_id":46800704340217,"sku":"f22110400ux0310","price":13.96,"currency_code":"CAD","in_stock":true},{"title":"21.5mm","offer_id":46800703815929,"sku":"f22110400ux0308","price":18.31,"currency_code":"CAD","in_stock":true},{"title":"20.5mm","offer_id":46800704209145,"sku":"f22110400ux0276","price":21.71,"currency_code":"CAD","in_stock":true},{"title":"13mm","offer_id":46800704012537,"sku":"f22110400ux0246","price":16.0,"currency_code":"CAD","in_stock":true},{"title":"14mm","offer_id":46800704274681,"sku":"f22110400ux0260","price":14.5,"currency_code":"CAD","in_stock":true},{"title":"15mm","offer_id":46800703947001,"sku":"f22110400ux0242","price":13.92,"currency_code":"CAD","in_stock":true},{"title":"16mm","offer_id":46800704307449,"sku":"f22110400ux0214","price":14.59,"currency_code":"CAD","in_stock":true},{"title":"17mm","offer_id":46800704176377,"sku":"f22110400ux0272","price":15.17,"currency_code":"CAD","in_stock":true},{"title":"18mm","offer_id":46800703848697,"sku":"f22110400ux0220","price":17.25,"currency_code":"CAD","in_stock":true},{"title":"19mm","offer_id":46800704372985,"sku":"f22110400ux0250","price":16.25,"currency_code":"CAD","in_stock":true},{"title":"20mm","offer_id":46800704143609,"sku":"f22110400ux0236","price":16.11,"currency_code":"CAD","in_stock":true},{"title":"21mm","offer_id":46800704078073,"sku":"f22110400ux0258","price":17.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_f22110400ux0308_ux_g03.jpg?v=1756729766","url":"https:\/\/www.harfington.com\/en-ca\/products\/p-1367211","provider":"Harfington","version":"1.0","type":"link"}
