{"product_id":"the-bore-set","title":"The Bore Set | 8-Piece TCT Tungsten Carbide Hole Saw Kit, 16-35mm","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eA hole is only a hole once it is round, clean, and exactly where you marked it.\u003c\/strong\u003e Everything else is damage you will be repairing later. The Bore Set exists for the moment a hole has to pass through sheet metal, and it is built from tungsten carbide rather than high speed steel for the simple reason that carbide keeps its edge through far more metal before it starts to wander.\u003c\/p\u003e\n\u003cp\u003eEach cutter is machined with multi-tooth gear geometry and carries its own centre alloy drill bit, which is what keeps the saw on the mark while the teeth bite. A spring on the pilot drill prevents the classic failure of hole sawing, the moment where the cutter grabs, stalls and spins the work instead. The cut is steadier in thin sheet, where high speed steel saws tend to tear through and leave an oval.\u003c\/p\u003e\n\u003cp\u003eThe set covers the sizes that ordinary jobs ask for, 16, 18, 20, 22, 25 and 35 mm, with eight pieces in the kit, a total weight of 830 grams, and a storage case that keeps the cutters from chipping each other in a toolbox. The teeth are rust proof, the material is hardened tungsten carbide alloy, and the whole kit is CE certified for metalworking use.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eMeasure twice.

It is equally at home in a home workshop where a single job justifies the kit, because a round hole with a clean edge is cheaper to buy once than to repair after a wander. Five common diameters in one case mean the job does not stall halfway through waiting on a second order, and the case keeps carbide teeth protected between jobs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-promise\" style=\"margin-top:30px;padding:18px 20px;border:1px solid #e6e6e6;border-radius:8px;background:#fafafa;\"\u003e\n\u003ch3 style=\"margin-top:0;\"\u003eThe EastSupplier Promise\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:8px 0;border-bottom:1px solid #eee;\"\u003e✦ Vetted supply.
