• Drill and tap bit combination: Thread size: M4 x 0.7, hex shank size: 6.35mm. The drill and tap bit combination set can complete drilling, tapping, deburring and countersinking. One-step operation greatly saves processing steps and improves work efficiency.
• Wide range of applications: Suitable for blind hole drilling. Used for tapping aluminum, die steel, stainless steel, bronze, hard plastic, etc. Recommended feed rate: General steel: 6-15m/min, Hard steel: 5-10m/min, Stainless steel: 2-7m/min, Cast iron: 8-10m/min.
• Easy to use: Self-centering eliminates the need for center drill or center punch assistance. Quick change 6.35mm hex shank is easier and safer to use with power tools. The tip of the hex shank is tapered to prevent excessive tapping.
• Titanium coating: Titanium coating provides excellent corrosion resistance, significantly increases wear resistance and hardness, and reduces the coefficient of friction. High speed steel tools have high hardness and toughness, wear resistance and heat resistance.
• Caution: Use with drills, tapping machines, CNC, and milling machines. When used in conjunction with tapping oil, you get better threads and more durable taps. For mechanical taps, we recommend using tap collets with overload protection.

Description: Combination drill and tap bit set can complete drilling, tapping, deburring and countersinking. One-step operation greatly saves processing steps and improves work efficiency.
Suitable for hole drilling. Used for tapping aluminum, die steel, stainless steel, bronze, hard plastic, etc.
Self-centering eliminates the need for center drill or center punch assistance. Quick change 6.35mm hex shank is easier and safer to use with power tools. The tapered end of the hex shank prevents excessive tapping. Exceed the tap to prevent thread damage due to excessive drilling.
High speed steel tools have high hardness and toughness, wear resistance and heat resistance. Titanium coating provides excellent corrosion resistance, significantly increases wear resistance and hardness, and reduces the coefficient of friction.
Use with excavators, tapping machines, CNC and milling machines. When used with tapping oil, you get better threads and more durable taps. Machine taps are recommended to be used with tap collets with overload protection.
If the feed speed is too fast, the torque will be large and the tap will be easily damaged. Taps are susceptible to chipping and breakage due to speed overload or non-perpendicular tapping. Micro taps (M1 to M3.5, etc.) are mainly used for tapping watches, wood, and soft metals with low hardness.
