Installed in The Spring Chuck of The Spindle：
When in use, the drill bit is installed in the spring chuck of the spindle. The clamping length of the twist drill on the spring chuck is 4-5 times the diameter of the drill shank to be clamped firmly.
Check The Concentricity of The Spindle and The Collet and The Clamping Force of The Collet:
1.Poor concentricity will cause small-diameter drills to break and inaccurate hole diameters.
2.Poor clamping force will cause the actual speed to be mismatched with the set speed, and slip between the chuck and the twist drill.
Check The Spindle Presser Foot:
The contact surface of the presser foot should be horizontal and vertical to the spindle without shaking to prevent broken drills and offset holes in the drilling.
Titanium Coated:
Smooth cutting surface
Advantages:
Improve the cutting accuracy, improve the wear resistance of the surface of the object, and prevent the surface of the object from oxidation and corrosion
Fully Ground:
Integral grinding and forming.
Advantages:
Smooth groove finish, high hardness, wear resistance.
High-speed Steel:
HSS 6542 steel
Advantages:
High hardness, high wear resistance and high heat resistance.
Twist drills can be clamped on Manual, Electric Drills, Drill Presses, and Lathes.
Suitable for Wood, Malleable Iron, Aluminum, Plastic etc.
Drilling holes must be kept clean, and coolant can be used for lubrication and cooling when drilling metal.

I have learnt the hard way, buy high quality drill bits otherwise they may not cut through metal etc. These are a good quality, highly recommended.

They are the correct size but that's the only positive, they are cheese grade Chineseium i had to sharpen them 3 times to drill 1 bolt and if you already tried to weld a nut to it don't bother you hardened the bolt to the point were it wont touch it

Used to trill and tap 10 mm X 1.0 LH threads. Worked great, took a long time to get (most likely due to COVID-19 and US government importation requirements).
