CZAR POWER Pro CZ-SD-4020 Step Drill Bit 4-20mm
The CZAR Power Pro CZ-SD-4020 Step Drill Bit is a professional-grade drilling tool designed for creating multiple hole sizes with a single bit, ranging from 4mm to 20mm. Manufactured from premium High-Speed Steel (HSS) and enhanced with a durable Titanium Nitride coating, this step drill delivers exceptional performance, extended tool life, and superior cutting efficiency across various materials.
The stepped cone design allows for progressive drilling of holes in different diameters without changing bits, making it ideal for electricians, HVAC technicians, metalworkers, and DIY enthusiasts. The TiN coating reduces friction, dissipates heat efficiently, and increases hardness, resulting in faster cutting speeds and longer tool life compared to standard uncoated bits.
Key Features:
- Wide Size Range (4-20mm): Single drill bit creates 9 different hole sizes, eliminating the need for multiple drill bits and reducing tool inventory costs
- Premium HSS Construction: High-Speed Steel provides excellent hardness, wear resistance, and ability to withstand high drilling temperatures without losing cutting edge
- Titanium Nitride Coating: Gold-colored TiN coating increases surface hardness, reduces friction, and extends tool life by up to 2 times over uncoated HSS bits
- Tri-Flat Shank Design: Three-sided shank provides maximum torque transmission, prevents slippage in chuck during heavy-duty operations, and ensures consistent drilling accuracy
- Stepped Cone Configuration: Progressive diameter increase allows for smooth, burr-free hole enlargement with minimal effort
- Versatile Material Compatibility: Works efficiently on sheet metal, aluminum, copper, brass, plastic, wood, and thin gauge steel up to 3-5mm thickness
- Universal Chuck Compatibility: Tri-flat shank fits standard 3-jaw drill chucks and provides superior grip compared to round shanks
- Automatic Deburring: Creates clean, professional-quality holes without secondary finishing operations
- Heat Resistant: TiN coating maintains cutting performance even under continuous high-temperature operations
