Set of 6 Silver rotary burr drill bits 3–8 mm, model 10417

Set of 6 Silver rotary burr drill bits 3–8 mm, model 10417 includes six precision-cut bits with diameters from 3 mm to 8 mm for use with rotary tools and handheld drills. The set is intended for drilling, deburring and shaping operations on a range of materials. Bits are sized to cover small to medium holes and detail work, making the set a compact selection for repair, fabrication and finishing tasks.

Advantages

The bits provide a selection of commonly used diameters that reduce the need to change tools frequently during a job. Their design supports efficient material removal and produces consistent hole sizes and edges when used at appropriate speeds. The compact set is easy to store and transport, and the variety of sizes increases versatility across metalworking, woodworking and plastics.

Suitable for

• Drilling small to medium diameter holes in metal, wood and plastic
• Deburring and edge finishing after cutting or machining
• Detail shaping and light material removal in repair and fabrication

Key specifications

• Number of pieces: 6
• Diameter range: 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm
• Intended tool type: rotary tools and handheld drills
• Primary materials: metal, wood, plastics

How to use

Select the bit size appropriate for the hole or shaping operation. Secure the bit in the chuck of a rotary tool or drill, ensuring a firm and centered fit. Set the tool speed according to the material: lower speeds for harder metals, moderate speeds for softer metals and plastics, and higher speeds for wood if recommended by your tool manufacturer. Apply steady, controlled pressure and allow the bit to cut without forcing. Retract periodically to clear chips and inspect progress. After use, clean the bits of debris and store them in a protective case to prevent damage.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. Match speed and feed to the material being worked on to prolong bit life. For metalworking, use cutting fluid or coolant to reduce heat build-up; for plastics, avoid excessive speed to prevent melting. Inspect bits before use for wear or damage and replace if cutting performance degrades.
