Description of π§ DWD13J LH SET High Speed Conventional Drill America
High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of toolholding systems. Reverse-flute drill bits run in the opposite (clockwise) direction from regular drill bits when making holes. 13 piece drill bit set comes in a metal case.
The description does not match the photo I bought in the picture as soon as I received the item because the picture did not match so it came I returned after reading the description and it matches the description but like I said it does not match the picture
These bits are harder to start, even with a decent center punch. First you need to start drilling with the right drill, and then switch to it. But I think you get what you pay for, next time pay more and buy something better.
