Conjunto de brocas Makita D-46202 18 peças

The Makita D-46202 18 pcs drill bit set provides a range of high-speed steel bits for general-purpose drilling in metal and wood. The set contains 18 sizes from 3 mm to 10 mm, enabling precise hole preparation for repair, installation and fabrication tasks. Bits are produced to deliver consistent diameter accuracy and edge retention for repeated use in workshop and on-site environments.

Advantages

The bits combine durable high-speed steel construction with a standard twist flute geometry that helps evacuate chips and maintain drilling speed. The wide size range in one compact set reduces time spent searching for compatible bits and supports quick changes between tasks. Each bit is ground to provide clean entry and controlled drilling progress in both wood and common ferrous and non-ferrous metals.

Suitable for

• Drilling holes in mild steel, sheet metal and aluminum
• Woodworking tasks including dowel and pilot holes
• General maintenance, repair and assembly work
• Portable drilling with hand drills and drill presses

Key specifications

• Number of pieces: 18
• Size range: 3 mm to 10 mm (standard increments)
• Material: high-speed steel (HSS)
• Flute type: standard twist flute for chip evacuation
• Shank type: straight round shank for chuck compatibility

How to use

Select a drill bit of the required diameter and secure it in the drill chuck, ensuring proper centring and tight clamping. When drilling metal, use a suitable cutting lubricant or coolant and moderate feed pressure; for wood, choose appropriate speed and steady feed to avoid splintering. Start with a pilot or centre punch mark on metal for accuracy, and back the bit out periodically to clear chips in deeper holes. After use, clean chips from the flutes and store the bits in the provided case to protect cutting edges.

Recommendations

Use appropriate drill speeds and feed rates for the material being drilled, and wear eye protection. For prolonged bit life when drilling metals, apply cutting fluid and avoid overheating. Store the set dry and avoid impact to preserve tip geometry.
