## Long description

The DeWalt DT6674-QZ cylindrical 5.5 mm drill bit is a general-purpose twist bit designed for drilling through common materials such as metal and wood. With a 5.5 mm cutting diameter and a straight cylindrical shank, this bit fits standard drill chucks and is suitable for use with handheld and bench drills. The geometry and construction of the bit are intended to provide reliable hole making for maintenance, construction and workshop tasks where straightforward, repeatable performance is required.
Advantages
This 5.5 mm cylindrical drill bit offers a consistent diameter and straight shank for secure chucking and stable drilling. It is manufactured to work on both metal and wood, reducing the need to change bits when moving between materials. The simple twist design provides predictable chip evacuation and straightforward sharpening when needed, making it suitable for routine repair and installation work.
Suitable for
Drilling holes in thin to medium-thickness metal sheets and plates
Creating pilot and clearance holes in soft and hard wood
General workshop and maintenance drilling tasks
Use with handheld drills and drill presses that accept cylindrical shanks
Key specifications
Cutting diameter: 5.5 mm
Shank type: cylindrical (straight) shank for standard chucks
Compatible materials: metal and wood
Typical applications: general-purpose drilling, pilot holes, clearance holes
How to use
Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the shank is clamped firmly to prevent slippage. Select an appropriate rotational speed and cutting fluid for the material: moderate to high speed for wood and lower speed with cutting oil for metal. Apply steady pressure, allowing the bit to cut without excessive force. Retract occasionally when drilling deeper holes to clear chips and reduce heat buildup. After use, inspect the cutting edges for wear and store the bit in a suitable holder to protect the tip.
Usage recommendations
For metal drilling, use cutting fluid and lower speeds to extend tool life. When drilling wood, higher speeds and light feed rates give cleaner holes. Replace or resharpen the bit when edges become dull to maintain hole quality and reduce the risk of bit wandering or excessive heat generation.
