Drill Bit Set Makita D-42385, 5 Pieces, 1/4 inch shank

Makita D-42385 drill bit set contains five drill bits with 1/4 inch shanks designed for use with 1/4" chucks and quick-change holders. The set is intended for general drilling tasks in wood, plastics and light metals depending on the bit geometry. The compact kit provides convenient storage and fast bit changes for both professional tradespeople and DIY users who need a small, portable selection of commonly used sizes.

Advantages

The 1/4 inch shank ensures compatibility with a wide range of drills, impact drivers and bit holders that accept hex shanks. Precision-ground flutes and balanced tips provide stable drilling performance and reduced wobble. The set's compact organiser keeps bits accessible and protected, minimising loss and simplifying transport. Durable material and heat-treated construction maintain cutting edges under typical use conditions.

Suitable for

• Drilling pilot holes in soft and hardwoods
• Through-holes and clearance holes in plastics
• Light metal drilling where appropriate bit geometry is used
• Quick bit changes with 1/4" quick-change systems and holders
• Portable toolkits for tradespeople and DIY repair tasks

Key specifications

• Number of pieces: 5
• Shank type: 1/4 inch (hex-compatible)
• Intended materials: wood, plastic, light metals (dependent on bit type)
• Storage: compact organiser case
• Typical applications: general drilling, pilot holes, clearance holes

How to use

Select a drill bit from the set that matches the hole diameter required. Insert the 1/4" shank into a compatible chuck or quick-change holder and ensure it is firmly seated. Start drilling at low speed to establish the pilot and then increase speed as appropriate for the material. For metals, use cutting fluid and moderate pressure; for wood and plastics, moderate speed with steady pressure is recommended. After use, allow bits to cool before returning them to the organiser to protect the cutting edges.

Usage recommendations

Match the bit geometry to the material: use brad-point or wood bits for clean holes in wood, twist bits for general-purpose work, and appropriately ground bits for light metal. Wear eye protection, clamp workpieces when possible, and avoid overheating the bits to prolong their life.
