Drill bit set Makita P-61391 25 pc(s)

The Makita P-61391 25-piece drill bit set is a collection of high-quality metal drill bits designed for precision drilling in a variety of ferrous and non-ferrous metals. The set covers a useful range of diameters to handle common workshop and construction tasks, and each bit is ground to provide accurate hole sizes and consistent cutting performance. The compact case keeps bits organized and protected for transport and storage.

Advantages

The drill bits are manufactured from hardened steel and feature precise tip geometry to reduce walking and improve centering on the workpiece. Uniform flute design ensures efficient chip evacuation and cooling during continuous drilling in metals. The assortment of sizes in one set reduces the need to purchase individual bits and supports rapid size selection on the job. Durable finishing resists wear and extends service life under normal workshop conditions.

Suitable for

• Drilling holes in steel, aluminium and other metal sheets
• Mechanical and maintenance shop tasks
• General assembly and installation work
• DIY metalworking and hobby projects

Key specifications

• Contents: 25 drill bits covering a range of small to medium diameters suitable for metalworking
• Material: hardened high-speed steel for wear resistance and stiffness
• Tip type: precisely ground point for accurate centering and reduced walking
• Flute design: spiral flutes for effective chip removal and heat dissipation
• Storage: compact plastic case for organization and transport

How to use

Select the appropriate drill bit size for the required hole diameter and secure the workpiece to prevent movement. Install the bit firmly in the drill chuck and set the drill to a speed suitable for the metal type and bit size. Apply steady pressure and allow the bit to cut without forcing; use cutting fluid when drilling harder metals to reduce heat and extend bit life. Clear chips periodically and finish the hole with a deburring tool if necessary.

Usage recommendations

For best results, match drill speed and feed to the metal being drilled, use cutting lubricant on thicker or harder materials, and replace worn bits to maintain hole quality and safety.
