These are good for bathroom projects where you have to mount mirrors and the like on top of tiles. The seven different sizes mean that you will have multiple sizes on hand to meet your drilling needs.\u003c\/p\u003e\u003cp\u003eThe shanks on thes holesaws are hollow so cooling water can be fed down the middle with the use of a water swivel. If you don't have a water swivel then use a spray bottle to keep them wet or drill the item slightly submerged in a large container. If that's not possible then use plasticine or Blu-tac to make a well around the hole and fill with water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCONTENTS OF SET\u003c\/strong\u003e\u003cbr\u003e3mm (1\/8\") diameter, 2.5mm shank\u003cbr\u003e4mm (5\/32\") diameter, 3.4mm shank\u003cbr\u003e5mm (13\/64\") diameter, 4.4mm shank\u003cbr\u003e6mm (1\/4\") diameter, 5.4mm shank\u003cbr\u003e7mm (4.4\/16\") diameter, 6.3mm shank\u003cbr\u003e8mm (5\/16\") diameter, 6.4mm shank\u003cbr\u003e9mm (5.7\/16\") diameter, 6.4mm shank\u003cbr\u003e10mm (3\/8\") diameter, 6.4mm shank\u003cbr\u003e11mm (6.9\/16\") diameter, 6.4mm shank\u003cbr\u003e12mm (1\/2\") diameter, 6.5mm shank\u003c\/p\u003e\u003cp\u003eThe nominal drilling depth for all is 25-30mm but you can go to a maximum 42mm if the core is removed before proceeding.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDRILLING TIPS\u003c\/strong\u003e\u003cbr\u003e1. Wet cutting is best. It reduces the amount of dust, flushes out the slurry so cuts a lot quicker and greatly extends the tool life by cooling the cutting edge.\u003cbr\u003e2. If you MUST dry cut then drill 5 seconds and rest 10 seconds to avoid overheating.\u003cbr\u003e3. Never use hammer action it is less effective and the holesaw may be damaged.\u003cbr\u003e4. Use a plywood template for cutting. You can secure the template to whatever you are cutting to ensure that it doesn't move from side to side. This is a very safe way to cut tiles or glass.\u003c\/p\u003e","brand":"THK - HK","offers":[{"title":"Default Title","offer_id":45131063984181,"sku":"T30687","price":19.9,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/8621\/files\/Desic-Diamond-Coated-Hole-Saws-10-Pieces-3-12mm-A_53b50005-43e6-4cd2-a2c9-50131b6cdd08.jpg?v=1776675104","url":"https:\/\/testntools.co.nz\/products\/desic-diamond-coated-hole-saws-10-pieces-3-12mm","provider":"Testntools","version":"1.0","type":"link"}
