amoolo AM0020013 Cobalt Drill Bits 1/16" 10pcs pneumatic accessory

1/16" Cobalt Drill Bit Set

This ten-piece set uses M35 cobalt high-speed steel containing five percent cobalt for greater hardness and wear resistance than standard HSS bits. The 135-degree split point prevents walking and eliminates the need for a centre punch. It suits DIYers and trade users drilling metal, stainless steel, plastic and wood.

Upgrade from standard HSS bits

The cobalt alloy handles higher heat and stays sharp longer in hard materials such as stainless steel and cast iron. The jump is worth it when drilling repetitive holes in tough alloys where ordinary bits dull quickly. Buyers who only drill soft wood or occasional plastic will not see the benefit.

Ten-piece pack for repeated tasks

Ten identical 1/16-inch bits give enough replacements for a full day of production drilling or multiple jobs without reordering. They comfortably handle sheet metal, aluminium alloy and softer metals at controlled speeds. The set runs out when larger diameters or specialised coatings are required.
