Hole saw Makita D-47139 9 pcs

The Makita D-47139 9 pcs hole saw set includes nine commonly used diameters designed for efficient and precise cutting of circular openings in a variety of materials. The set is intended to provide clean, consistent holes for tasks such as installing pipework, creating cable entry points, mounting fixtures, and other trade or home improvement applications. The saws are made to fit compatible arbors and drivers and are balanced for steady rotation during use.

Advantages

This 9-piece hole saw set offers durability and reliable performance across different materials. The saws are engineered for accurate cutting with reduced burrs and minimized chipping at the edges of the hole. The selection of sizes in the set covers common installation requirements, which reduces the need to switch tools frequently. The construction aims to deliver long service life under normal working conditions and stable attachment to standard power tool arbors.

Suitable for

• Cutting holes in wood for door hardware, plumbing, and wiring
• Making openings in drywall and plasterboard for electrical boxes and fixtures
• Drilling through soft metals and plastics where clean circular cuts are required
• General maintenance, renovation, and installation tasks in residential or commercial settings

Key specifications

• Set composition: nine hole saws covering a range of common diameters
• Material compatibility: wood, drywall, soft metals, plastics (subject to correct speed and feed)
• Design: bi-metal construction for a balance of cutting performance and durability
• Mounting: suitable for use with standard hole saw arbors and compatible power drills
• Typical applications: plumbing, electrical, HVAC, carpentry, and general installations

How to use

Select the hole saw diameter appropriate for the required opening and fit it to a compatible arbor that matches your drill. Mark the center of the hole on the workpiece and, if available, pilot-drill a small guide hole to locate the arbor pilot. Secure the workpiece and set the drill to a speed suitable for the material being cut. Begin cutting with steady pressure, allowing the saw teeth to do the work and avoiding excessive force which can cause binding or overheating. Clear chips periodically to maintain cutting efficiency and complete the cut by withdrawing the saw once the hole is through. After use, remove metal or wood debris from the saw teeth and store the set in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, gloves, and hearing protection. Match drill speed and feed to the material type—lower speeds for metals, moderate speeds for hardwoods, and higher speeds for softwoods and plastics. When cutting thicker or harder materials, use light, controlled passes and allow cooling breaks to prevent premature wear. Ensure the arbor pilot is properly centered to reduce runout and obtain a clean, accurate hole.
