Hole saw drill bit

Start by identifying the target materials: drilling in wood, plastic, and light metals. Check the bit specifications, as they confirm the cutters are designed to open precise circular holes. Then determine the required diameter. The listing includes small arms that accept from 14 mm to 30 mm, and large arms that accept from 32 mm up to 210 mm. You’ll also find SDS Plus core cutters in different sizes and with high-quality materials, giving you multiple options for workshop and home projects.

Small arbors accept holes from 14 mm to 30 mm and are suited for small to medium projects, while large arbors accept holes from 32 mm to 210 mm and are better for larger openings in walls or thick surfaces. Choose based on the hole diameter you typically need, and make sure the drill is compatible with the common SDS Plus system to ensure stability and accurate results while drilling.

The 40 mm and 50 mm sizes are for Core Drill Bit models that come with a guide center tip to ensure accurate hole starting and prevent slipping. These bits are designed for light metals and wood, allowing you to start drilling quickly with steady torque—important for installation and piping projects, especially when fitting larger mounting elements or infrastructure components.

An SDS Plus arbor securely connects the drill bits to the drill or tool, allowing safe connections to the rotating shaft. It provides the right size thread: 1/2"-20UNF for the smaller shank and 5/8"-18UNF for the larger shank. This ensures compatibility between the hole saw cutters and the dedicated bits from 14 mm up to 210 mm. Using the correct arbor also makes it easier to change the cutters and reduces wear or damage to the drill equipment.

This set is suitable for multi-purpose workshops and covers a wide range of sizes and systems—from cutters with 14 mm to 210 mm and additional SDS Plus bits—so you can drill accurately and efficiently in wood, plastic, and light metals. Having both small and large arbors gives you high flexibility when dealing with different hole shapes and diameters, making it a practical and comprehensive option for any workshop.

Store the bits in a tightly packed, dry package and keep them away from moisture and dust exposure. Clean the surfaces after each use, and make sure all cutters are clean and free of debris before placing them back in the case. Use the right arbor and confirm compatibility with the required cutter size to avoid damage during operation. Avoid hitting the cutters on hard surfaces during storage or transport to protect against chipping and wear.
