{"product_id":"magnetic-soft-jaws","title":"Magnetic soft jaws for a bench vise, pair","description":"\u003cp\u003eSteel vise jaws are hardened and cut with teeth, because they are designed to not let go. That is exactly what ruins a finished part - you tighten, the teeth bite, and now there are two rows of dents in a surface you spent an hour on.\u003c\/p\u003e\n\u003cp\u003eRubber-faced pads on an aluminium backing, held on by magnets. They go on in a second and come off in a second.\u003c\/p\u003e\n\u003ch3\u003eTwo faces, two jobs\u003c\/h3\u003e\n\u003cp\u003eFlat is for flat stock - sheet, bar, a finished face you do not want marked.\u003c\/p\u003e\n\u003cp\u003eV-groove is for anything round. A round part in flat jaws touches on two lines and rolls under load. The V holds it on four, so it sits on the axis and stays there. If you are drilling across a rod, this is the difference between a hole through the centre and a hole that wanders off the side.\u003c\/p\u003e\n\u003ch3\u003eWhere it stops\u003c\/h3\u003e\n\u003cp\u003eRubber compresses. A soft jaw is a compromise between holding and marking, and it holds less than steel does - it will slip before steel slips, and the answer is not to crank harder, because crushing a part in soft jaws is just as easy as denting it in hard ones.\u003c\/p\u003e\n\u003cp\u003eHeat and solvents are hard on rubber. Do not clamp a part you have just heated, and keep acetone off them.\u003c\/p\u003e\n\u003cp\u003eThe magnets hold the pads to the jaws, not the work to the pads. Check they are seated flat before you tighten - a pad that is half on is worse than no pad at all.\u003c\/p\u003e\n\u003cp\u003eMeasure your vise jaw width before ordering. These are sold by that width, not by the vise's nominal size.\u003c\/p\u003e","brand":"Mikrabench","offers":[{"title":"4 inch \/ Flat","offer_id":47512868847807,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true},{"title":"4 inch \/ V-groove","offer_id":47512869601471,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true},{"title":"5 inch \/ Flat","offer_id":47512869634239,"sku":null,"price":22.99,"currency_code":"USD","in_stock":true},{"title":"5 inch \/ V-groove","offer_id":47512869667007,"sku":null,"price":22.99,"currency_code":"USD","in_stock":true},{"title":"6 inch \/ Flat","offer_id":47512869699775,"sku":null,"price":24.99,"currency_code":"USD","in_stock":true},{"title":"6 inch \/ V-groove","offer_id":47512869732543,"sku":null,"price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5826\/3743\/files\/S75ca0472b7ec463eb509044aa89febaf0.webp?v=1789875368","url":"https:\/\/arvonelle.com\/products\/magnetic-soft-jaws","provider":"ARVONELLE","version":"1.0","type":"link"}
