I tried with different angles, it is good and easy to use. Be careful when drilling holes over 8 mm on hard metals. Stabilize your object.

良質
非常に良い品質。
Excellent tool for creating 3mm to 12mm holes. Step drill bit, with hole cutting size written on each step.
good value
Very high quality. Starts with 3mm diameter bit, that makes very easy to start centered any hole. High hardness, drills very smooth through 316SS 2mm thick sheet. Much better than other step drill bits I already have. Hope it will last for a long time. Hex shaft is very convenient to use with electric power tools or with screwdriver handle. Very happy with it.
bon pour le prix meme si je l'ai fait rougir dans 2mm de damas titane
