## Summary description

GRAPHITE step-less drill bit 4–32 mm (model 57H741) provides an adjustable cutting diameter in a single tool. Designed for drilling a range of hole sizes without changing bits, it suits work in metal and wood where variable diameters are required. The bit is practical for maintenance, installation, and workshop tasks needing flexible hole sizing.

## Long description

GRAPHITE step-less drill bit 4–32 mm (57H741) is an adjustable cutting tool designed to create a wide range of hole diameters with a single bit. The bit features a continuously adjustable cutting edge that allows precise selection of hole size from 4 mm up to 32 mm. It is produced for use in handheld drills and drill presses and is intended for drilling through metal and wood where variable diameters are needed for installation and maintenance tasks.
Advantages
The step-less design eliminates the need to change multiple bits when drilling different diameter holes, saving time and reducing tool inventory. A single adjustable cutter provides a smooth, concentric hole with reduced vibration compared with multiple stepped bits. The bit is built to provide consistent cutting performance in both metal and wood, offering durability and repeatable hole sizing. Its adjustable nature supports fine tuning of the hole diameter to fit fasteners, grommets, or fittings precisely.
Suitable for
Drilling variable-diameter holes in thin and medium-thickness metal sheets
Creating clearance and installation holes in wood and wooden panels
Maintenance and repair work where on-site hole-size adjustment is required
Workshop tasks that require multiple hole sizes without frequent bit changes
Key specifications
Adjustable drilling diameter range: 4–32 mm
Compatible with handheld drills and drill presses
Suitable materials: metal and wood
Continuous (step-less) cutting adjustment for precise sizing
Designed for cutting through thin to medium-thickness workpieces
How to use
Secure the workpiece properly and mark the required hole centre. Install the step-less drill bit in the drill chuck and tighten securely. Rotate the adjustable cutter to set the desired diameter, verify the setting against a gauge or template if exact size is critical, and clamp the workpiece. Use appropriate drill speed and cutting fluid for metal; for wood select a speed suitable for clean cutting. Apply steady pressure and keep the drill perpendicular to the work surface. After drilling, stop the tool before removing the bit to avoid damage to the cutting edges.
Usage recommendations
Use cutting fluid or lubricant when drilling metals to extend tool life and improve chip evacuation. For best results in wood, ensure the workpiece is clamped and the cutting edges are sharp. Check diameter settings periodically during repeated operations and avoid side loads that can bend or dull the adjustable cutter.
