Precision step drill for combining hole making with a second diameter, chamfer or counterbore feature in one tool. Variants include different dimensions, geometries and coating options.
Selection Guide
Confirm the first cutting diameter and length.
Confirm the second diameter / step dimension and required angle.
Check shank diameter and overall length for holder and reach compatibility.
Choose the coating or finish that matches the workpiece application shown for the selected variant.
Why Use a Step Drill?
A correctly selected step drill can combine multiple hole features in one operation and reduce tool changes when the required geometry matches the cutter.
Solid Carbide Step Drill
Precision solid-carbide step drill for combined drilling and chamfering in a single operation. Available in 90° and 180° configurations, with DLC-coated and bright-finish options depending on the selected variant.
Key Features
Combines drilling and chamfering to reduce tool changes and cycle time.
Solid-carbide construction for rigidity, wear resistance and stable cutting.
Two-step geometry supports accurate hole and counterbore/chamfer formation.
DLC-coated variants are suitable for non-ferrous materials such as aluminum.
Specification Example
1 × 5 × D4 × 10 × 50 means d = 1 mm, first cutting length = 5 mm, D2 = 4 mm, second cutting length = 10 mm, overall length = 50 mm.
Applications
Suitable for CNC machining centers and engraving machines. Depending on coating and geometry, typical applications include aluminum alloys, copper, plastics, acrylic and related non-ferrous materials.
Note: Exact angle, coating and dimensions vary by variant. Please confirm the selected variant before ordering.
FAQ
What do 90° and 180° refer to? They identify the step/cutting geometry offered by the product variants. Confirm the exact variant against your drawing.
