 How to install these square drill bits?

Step 1: The drill core is very sharp. Wear working gloves to avoid direct contact between your hands and the drill bit during installation.

Step 2: Put the square drill shell and drill core into the jig of the square tenoning machine, and then hold the square hole drill bit by hand.

Step 3: Take 0.5~1mm thick sheet (metal sheet or plastic sheet) and jam it at the step of the drill shell. After fixing the drill core, remove the sheet, then adjust the angle of the drill shell to the top to ensure clamping, so that a 0.5~1mm gap can be formed between the drill core head and the inner bevel of the drill shell, which can prevent the bit from jamming during use.

Customer Reviews

 There is a little bit of a learning curve based on the wood that you are using. I had never used these types of bits before, but I quickly realized that in order to effectively drill mortise/tenon joints without having to spend a ton of time chiseling, I could just measure and drill small pilot holes spaced just inside the span of each bit. Huge time saver! They are sharp and ready to work.

Got what I paid for.
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
I dropped my drill with the bit installed. It broke quite easily. It was a relatively inexpensive so I can't complain. A higher quality harder metal would have earned 5 stars.
