Drill bit set Dedra WIT01034 — 1 mm diameter, 34 mm length, 3 pcs, for metal

Dedra WIT01034 is a set of three 1 mm diameter drill bits with a 34 mm overall length, designed specifically for drilling metal. These small-diameter bits are intended for precise, controlled drilling where accuracy and clean holes are required. The compact length and slim profile make the set suitable for access to confined areas and for tasks that require minimal material removal.

Advantages

The set delivers consistent diameter and straightness across all three bits, enabling repeatable results during series work. Their 1 mm tip is optimized for fine hole drilling in thin metals and delicate components. Supplied as a three-piece pack, the set provides immediate replacements for frequent use and reduces downtime due to breakage. The short 34 mm length improves stability and reduces flexing compared with longer micro-drills.

Suitable for

• Precision metalworking and model making
• Electronics chassis modification and PCB mounting holes (thin panels)
• Thin-sheet fabrication and small fastening holes
• Hobby projects requiring small, accurate drilled holes

Key specifications

• Diameter: 1 mm
• Overall length: 34 mm
• Material compatibility: metal (thin sheets, light gauge steel, aluminum, brass)
• Quantity in set: 3 pieces

How to use

Secure the workpiece in a vice or clamp to prevent movement. Select an appropriate drill press or hand-held rotary tool with a compatible chuck and ensure it can hold a 1 mm shank securely. Mark the drilling point and, if necessary, create a small center punch dimple to guide the bit. Begin drilling at low speed with light pressure, allowing the bit to cut gradually and reducing the risk of bending or breakage. Withdraw the bit periodically to clear metal chips and apply a light cutting lubricant for harder metals. Replace bits from the set when wear or dulling is detected.

Usage recommendations

Use low to moderate spindle speeds and steady feed pressure for the best hole quality. For stainless steel or harder alloys, apply cutting fluid and increase chip evacuation frequency. Store the bits in a protected case to avoid tip damage and handle them carefully to prevent bending.
