Solid Carbide Step Drill | 90° / 180° | DLC Coated

Solid Carbide Step Drill | 90° / 180°

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.
