Q: What drill bit should be used to process a 1.5 hole with a hole depth of 12 and a material of 00Cr13Si2?

A: If the equipment has internal cooling, it is recommended to use ADO-MICRO 12D.

Q: What good recommendations are there for processing copper parts?

A: It is recommended to use the corresponding EX-SUS series of high-speed steel drill bits.

Q: Can a heat shrink shank be used for small holes within D2? Will the drill bit break?

A: The ADO-MICRO series can all use heat shrink shanks. There are many reasons for broken drill bits that require careful elimination and analysis on site.

Q: How are alloy and powder high-speed steel applications classified?

A: Simply put, the alloy referred to by the tool material is a hard alloy, and powder high-speed steel is a type of high-speed steel. They are two materials with completely 

different properties.

Q: Can high-speed steel drill bits be sharpened? Can they be sharpened by hand?

A: The EX-SUS series can be manually sharpened, but the original chisel edge pattern cannot be achieved by hand, and the coating on the blade will also be gone, so the 

performance will be much worse than a new product.
