Why choose the 08X series TCT hole saw? (Benefits and performance)
The key to this drill saw's exceptional performance lies in its robust construction and the quality of the materials used. The saw body is made of high-quality #45 HCS steel with a thickness of 1.5 mm, which prevents deformation during demanding drilling. The cutting teeth are made of tungsten carbide with 6% cobalt (YG 6X tungsten steel), which provides exceptional resistance to wear and overheating.
The special cutting edge geometry with multiple forked inserts effectively shreds and removes material from the cutting area. This reduces friction, prevents clogging and significantly increases drilling speed. With a cutting depth of up to 60 mm, you can even handle thicker workpieces in a single pass.

Frequently Asked Questions (FAQ)
For which materials is the TCT 68mm hole saw suitable?
Thanks to the tungsten carbide teeth (YG6X) and the HCS body, this saw is extremely versatile. It can be successfully used for drilling in wood, wooden furniture panels, plastic (PVC), metal and mineral materials such as cellular concrete (siporex), silicate bricks and ceramic tiles.
What chuck (adapter) do I need for this hole saw?
For a 68 mm diameter hole saw (which uses a 5/8" thread), we recommend using the 08X002 chuck (HEX 10 mm 5/8") for classic drills or the 08X003 chuck (5/8" SDS+) for use with SDS+ hammer drills.
Can I use this hole saw with an impact drill?
Yes, you can use the core saw with a hammer drill (using the SDS+ adapter 08X003), but you must switch the device to the rotation mode without impact (drilling without impact). The impact function could damage the carbide teeth of the saw.
