Drill Bit Set Makita P-61385 — HSS-G TiN, 19 pcs, sizes 1–10 mm

Makita P-61385 is a 19-piece drill bit set manufactured from high-speed steel (HSS-G) with a titanium nitride (TiN) coating. The set contains metric sizes from 1 mm to 10 mm in incremental steps, designed for drilling into metals and general workshop applications. The TiN coating increases surface hardness and reduces wear, which helps maintain cutting performance and extend service life during repeated drilling operations.

Advantages

The HSS-G substrate provides good toughness and heat resistance for standard metalworking tasks, while the TiN coating adds improved hardness and friction reduction at the cutting edge. The included size range (1–10 mm) covers common drill diameters for assembly, maintenance and fabrication work. Uniform flute geometry and ground tips support precise chip evacuation and accurate centring on metallic surfaces. The set is supplied as a compact collection of bits suitable for organized storage in a workshop environment.

Suitable for

• Drilling holes in steel, cast iron and non-ferrous metals
• General workshop maintenance and mechanical assembly
• Preparing pilot holes for screws and fasteners
• Repeated production or repair tasks requiring durable bits

Key specifications

• Material: High-speed steel (HSS-G)
• Coating: Titanium nitride (TiN)
• Number of pieces: 19
• Size range: 1 mm to 10 mm (metric, incremental sizes)
• Tip style: Ground point for metal drilling
• Typical application: Metalworking and general workshop use

How to use

Select the appropriate drill diameter for the required hole and secure the workpiece to prevent movement. Install the chosen Makita P-61385 bit in a compatible drill chuck and tighten firmly. Use moderate feed pressure and appropriate spindle speed for the material: lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply cutting fluid when drilling steel to reduce heat buildup and extend bit life. Withdraw the bit occasionally to clear chips and avoid clogging the flutes.

Usage recommendations

For best results, match drill speed and feed to the workpiece material and use cutting lubricant when machining steel. Inspect bits for wear or damage before use and replace worn bits to maintain hole quality. Store the set in a dry place to protect the TiN coating and avoid corrosion of the bit shanks.
