So we sell them the other way round — one size, ten bits, and you buy the size you use.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTungsten carbide, 3.175 mm (1\/8 inch) shank.\u003c\/strong\u003e Fits the drill press collet and every rotary tool.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e38 mm long, 10 mm flute.\u003c\/strong\u003e Standard PCB bit geometry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColoured collar per size\u003c\/strong\u003e so you can grab the right one without a caliper.

A 0.5 mm bit breaks from speed and from sideways load, not from pressure - so run it slow, let it clear, and do not lever the part. Ten in a pack is not us being generous, it is how many you will get through.\u003c\/p\u003e\u003ch3\u003eIf they arrive broken, that is on us\u003c\/h3\u003e\u003cp\u003eCarbide micro bits sometimes lose a tip in the post - the tube is small and the parcel is not handled gently. Open the pack and count them. If any arrived snapped, tell us the size and we send a replacement pack. Nothing to return and no photograph of a shipping label required.\u003c\/p\u003e\u003ch3\u003eDelivery on this item\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003e6 to 10 business days.\u003c\/strong\u003e These ship from a stocked warehouse, not from the workshop, so they are faster than the machine.
