The supplier does not sell it as a bundle, so it is simply both sets ordered together and it may arrive as two parcels. It is priced below the two bought separately — the saving is the difference against the crossed-out price above.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eWhat is the difference between the two finishes?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eThe silver set is bare high-speed steel. The gold set is the same cutter with a titanium coating, which in general runs a little cooler and holds an edge longer. \u003cstrong\u003eThis maker publishes no figure for it\u003c\/strong\u003e, so we are not going to tell you it lasts three times as long. If you want the usual answer: coated is worth it if you cut steel often, uncoated is fine for aluminium, plastic and wood.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eHow thick a material will they go through?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eThe maker does not say, and we are not going to guess on a cutting tool. What we can tell you is what it is: an uncoated HSS cup with a pilot. That is a sheet-and-plate tool — electrical boxes, panels, trunking, conduit plates, plywood and board. If you are drilling structural steel, buy a bi-metal or carbide cutter from a brand that prints the number.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eDo I need a separate arbor?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eNo. Each of the five arrives as a complete assembly — cutter, arbor, pilot drill, ejector spring and grub screw — and there is a hex key for each one. You are not buying a set of cups that then needs a mandrel.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eWhat is the spring for?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eIt pushes the slug out. Without it the disc you have just cut sits inside the cup and you spend the next minute poking it out with a screwdriver.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eWhat speed should I run them at?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eThe maker gives no RPM. General practice for HSS is slow and steady — the bigger the cutter, the slower — with firm pressure and cutting fluid on steel. Running one fast and dry is the usual way to ruin the teeth on the first hole.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eWill they cut stainless?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eThe maker lists stainless among the materials. Uncoated HSS on stainless is hard work: slow speed, real pressure, and fluid, or it work-hardens and stops cutting. The coated set is the better pick if stainless is why you are buying.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eWill it go through tube or pipe?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eYes, and it is one of the jobs these are good at — a cable entry into a square post, a drain in a tube. Two things change: \u003cstrong\u003eclamp the tube\u003c\/strong\u003e, because a round section wants to spin the moment the teeth bite, and expect the cutter to grab as it breaks through the far wall. Go slower than you would on flat sheet.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eCan I use them in a hand drill?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eYes, and that is what the photographs show. A corded drill or a decent cordless on its lowest speed. Hold it square — the pilot keeps it centred but it will not keep it straight for you.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #E3E6EA;padding:14px 0\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;font-size:16px\"\u003eAre the pilot bits replaceable?\u003c\/summary\u003e\u003cp style=\"margin:12px 0 0\"\u003eYes. The pilot sits in the arbor and is held by the grub screw, which is what the hex key is for. The pilot is the part that usually gives up first.\u003c\/p\u003e\u003c\/details\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"background:#F4F5F6;border-radius:14px;padding:30px 28px;margin:0 0 24px\"\u003e\n  \u003cp style=\"color:#E5622A;font-size:12px;letter-spacing:.18em;text-transform:uppercase;font-weight:700;margin:0 0 10px\"\u003eShipping \u0026amp; returns\u003c\/p\u003e\n  \u003cp style=\"margin:0 0 10px\"\u003e\u003cstrong\u003eDelivery in 7–15 business days\u003c\/strong\u003e from the time you order — that window already includes the 1–2 business days we take to process.
