Drill Bit Set Makita D-42488 — 5 HSS Twist Bits for Metal and Wood

Makita D-42488 is a set of five HSS twist drill bits designed for drilling in metal and wood. The kit contains five high-speed steel bits suitable for handheld drills and drill-press use, providing reliable cutting performance and wear resistance for a range of maintenance, workshop and construction tasks.

Advantages

The HSS construction delivers a balance of hardness and toughness for effective cutting in both metal and wood. The set format provides a selection of commonly used sizes in a single package, simplifying tool selection for general-purpose drilling. Compatibility with standard drill chucks makes the bits convenient to use with handheld drills and bench drills without additional adapters. The high-speed steel material contributes to longer life under typical working conditions and consistent drilling accuracy.

Suitable for

• Drilling holes in mild and non-hardened metals
• Drilling through wood and wood-based materials
• General maintenance and repair tasks
• Workshop and light construction applications

Key specifications

• Number of pieces: 5 HSS twist drill bits
• Material: high-speed steel (HSS)
• Intended materials: metal and wood
• Compatibility: suitable for handheld drills and drill presses with standard chucks

How to use

Select a drill bit size appropriate for the hole diameter required and ensure the drill is switched off before inserting the bit. Secure the bit in the drill chuck and tighten according to the drill manufacturer’s instructions. When drilling metal, use a suitable cutting fluid or lubricant at moderate speeds to reduce heat and extend bit life. For wood, use appropriate rotational speed and steady feed to avoid tear-out. Keep the workpiece clamped or secured and wear recommended personal protective equipment while operating power tools.

Usage recommendations

Use appropriate speeds and feed rates for the material being drilled, apply cutting fluid when working with metal, and replace bits that show significant wear or chipping to maintain drilling quality and safety.
