Drill bit set Makita D-72849 suitable for metal wood

The Makita D-72849 drill bit set is designed for drilling in metal and wood and includes a range of sizes to cover common drilling tasks. Manufactured from hardened materials suitable for repeated use, the set aims to deliver consistent hole quality and reliable cutting performance across different substrates. The bits are intended for use with standard drill chucks and for both handheld and machine-mounted drilling operations.

Advantages

The set combines multiple diameters to reduce the need for frequent bit changes and to support stepwise widening of holes. Precision-ground cutting edges improve centring and reduce wandering on the workpiece, while heat-treated construction increases resistance to wear during extended use. Compatibility with standard chucks and a compact storage case (when included) helps to keep bits organised and accessible on job sites.

Suitable for

• Drilling holes in mild and soft steels and non-ferrous metals
• Woodworking tasks including pilot holes and through-holes
• General maintenance and repair work in workshops and at home
• Preparation of holes for fasteners, rivets and dowels

Key specifications

• Application: metal and wood drilling
• Material: hardened high-speed steel or equivalent hard metal construction for cutting and wear resistance
• Tip: precision-ground point for improved centring
• Shank type: standard cylindrical shank compatible with common drill chucks
• Range of diameters: multiple sizes included to cover common hole diameters (set includes several bit sizes)
• Finish: protective coating or untreated depending on bit type to reduce corrosion and friction

How to use

Select the appropriate drill bit diameter for the required hole size and secure it in the drill chuck, ensuring it is tightened correctly. For metal, mark the drilling point and use a centre punch if necessary to prevent bit walking; start at low speed to establish the hole and apply steady pressure, increasing speed as appropriate. For wood, choose higher speeds and moderate pressure; consider pilot holes for large fasteners. Use cutting fluid or lubricant when drilling harder metals to reduce heat and extend bit life. After use, clean chips from the flutes and store bits in their case to prevent damage.

Usage recommendations

When drilling metal, use a lubricant and moderate feed to minimise overheating. Replace bits that show significant wear or chipping to maintain hole quality. Match drill speed and feed to material type and bit diameter for best results; larger diameters generally require slower speeds.
