Milling drill bit Proxxon 28761, 3 mm diameter, single piece

Proxxon 28761 milling drill bit, single piece with 3 mm diameter, is a precision cutting tool intended for small-scale workshop and model-making applications. Manufactured for use in compatible hand drills, micro-drills and small drilling machines, this single 3 mm milling drill bit is suitable for machining metal, wood and plastics when paired with appropriate equipment and cutting parameters. The tool's compact size and single-piece supply make it convenient for tasks requiring fine holes and shallow milling slots.

Advantages

The 3 mm diameter and single-piece construction ensure tight dimensional control and straightforward replacement. This milling drill bit is designed to provide clean cutting edges and reliable concentricity in miniature drilling and milling operations. Its compatibility with a range of small drilling devices allows consistent performance across different materials when used with proper speeds and feeds.

Подходит для

• Моделирование и макетирование
• Мелкая механическая обработка и ремонт электроники
• Сверление и фрезерование в дереве для точной подгонки
• Обработка пластика и тонких металлических деталей

Key specifications

• Cutting diameter: 3 mm
• Quantity: single piece
• Intended materials: metal, wood, plastics (application depends on machine and feed)
• Tool type: milling drill bit for small/precision drills

How to use

Install the 3 mm milling drill bit into a compatible chuck or collet, ensuring secure and concentric clamping. Select appropriate spindle speed and feed rate for the work material—higher speeds for small-diameter carbide or high-speed steel bits in plastics and soft metals, lower speeds for harder metals. Use light, steady feed and clear chips frequently to avoid clogging and overheating. Reduce side loads and avoid aggressive plunging to preserve bit life. Wear eye protection and follow machine safety guidelines.

Usage recommendations

Use suitable cutting lubricant or coolant when machining metals to extend tool life; for wood and plastics, minimize heat buildup by adjusting speed and clearing chips. Check chuck runout before working to maintain hole accuracy and replace the bit when wear degrades cutting performance.
