## Long description

Step Drill Bit Silver 4–45 mm model 11301 is a conical stepped drill designed for progressive enlargement of holes in thin sheet materials and nonferrous metals. The single-piece tool covers a drilling range from 4 mm up to 45 mm, combining multiple step diameters so users can size holes without frequently changing bits. The geometry of the steps and the cutting edges is suited to fast, controlled cutting in thin metal sheets, plastic panels and light alloy components.
Advantages
The stepped design provides an extended range of hole diameters in one tool, which speeds up work and reduces tool changes. Smooth step transitions and a pointed tip allow precise centering and initial penetration, while the stepped flutes evacuate chips to maintain cutting efficiency. Compatibility with standard drill chucks and power drills makes the bit versatile for workshop and on-site use.
Suitable for
 Progressive hole enlargement in thin sheet metal
 Electrical installations and cable gland holes
 HVAC duct and panel work
 Plumbing fixtures and light metal fabrication
 General workshop drilling tasks in nonferrous materials
Key specifications
 Drilling range: 4–45 mm in stepped increments
 Type: conical step drill bit for progressive hole sizing
 Material compatibility: thin steel sheets, aluminium, brass, copper, plastics
 Shank type: compatible with standard drill chucks
 Cutting style: multi-step cutting edges for sequential hole enlargement
 Recommended use: light to medium duty sheet and plate work
How to use
Mark the desired hole center, clamp the workpiece securely to prevent movement and start drilling at low speed to establish a clean entry without wandering. Use cutting lubricant when working with metals to reduce heat and wear. Progressively advance through the steps until the required diameter is reached; do not apply excessive axial force—let the cutting edges do the work. Clear chips periodically to prevent clogging and maintain cutting performance.
Usage recommendations
For best results, use the step drill bit with a variable-speed drill and appropriate cutting fluid when drilling metals. Secure thin sheets to a backing board to reduce vibration and deformation. If a clean finishing edge is required, deburr the hole after drilling.
