The HYCHIKA philosophy is to focus on customer needs, striving to combine technology and strength in their tools, creating high-quality products at competitive prices.

From the brand's power tools offerings, customers – men, women, and the elderly alike – can find convenient tools to achieve and even exceed their goals.

The Bi-Metal Hole Saw Set 6.2A is a versatile 3/4" to 2-1/2" hole saw kit that includes mandrels, adapters, a hex key, a drill bit, and a storage case. The bi-metal material can offer up to 50% longer life and is rust-proof, while the high-speed cutting (around 500°C) maintains high hardness. The knife-edged teeth provide clean and precise cutting.

To replace the center drill bit, first remove the hexagonal wrench, align the shorter end with the hole on the connecting mandrel, turn it counterclockwise, insert a new drill bit, and tighten it back with the wrench.

This 11-piece bi-metal hole saw set with 2 mandrel sizes can meet all drilling needs, suitable for a wide range of materials such as wood, PVC, plating, plywood, pipes, plastics, plasterboard, soft plaster, cornhole boards, and thin metal. The hole saws are perfect for diverse professional and general projects at home, in the yard, hospital, hotel, factory, or outdoors.

For optimal performance, add coolant or water to prevent high tooth tip temperatures from cracking the cutting edge. Drill slowly when the pilot bit goes through the material, and ensure the cutting material is fixed at a 90-degree angle to the hole saw. Before use, choose the right speed for tapping.

If the hole opener behaves abnormally during use, stop drilling immediately. Avoid over-tightening the screws and remove debris from the teeth to improve cutting efficiency.

The HYCHIKA Bi-Metal Hole Saw Set offers superior quality and versatility, with bimetallic construction, high-precision cutting, and a comprehensive 11-piece kit with accessories. For customers who only need to cut softer materials like cork boards, thin PVC boards, drywall, and plywood, HYCHIKA also offers a 19-piece Hole Saw Kit as an alternate option.
