Description of Masterpiece: Unyielding Strength of the Multi Hardened Carbon Steel
Spade Drill Bit set includes six commonly used sizes as listed below. Bit Set includes the following sizes 3/8", 1/2", 5/8", 3/4", 7/8", & 1" all with a 1/4" SHANK. Designed to fit the majority of Drill brands currently on the market. Extra long Bit shanks - exceeds 12 inches.
These industrial drill bits failed to meet my expectations in terms of durability and precision. Through trial and error, I found that the bits struggle to maintain a sharp edge and often break under moderate pressure. While they are affordable, the cost in wasted time and additional replacements far outweigh the initial savings. As an Industrial and Scientific customer, I cannot recommend these bits for heavy-duty use.
Previously only used a 1 inch diameter drill bit needed to run wires through the wall. Seems pretty solid, works well with both corded and cordless chucks.
