Frequently Asked Questions (FAQ)
1. What materials are these flat drill bits suitable for?
The drill bits are primarily intended for roughing softwood (e.g. spruce, fir, pine), drilling into chipboard, plywood and other similar wood materials. They are also excellent for drilling into plasterboard (gypsum board), furniture elements and various types of plastic.
2. What is the advantage of the HEX clamping over the classic cylindrical clamping?
The HEX (hexagonal) chuck prevents the drill bit from rotating or slipping in the drill head under heavy load. It also allows for extremely quick and easy drill bit changes without the use of additional tools, which is extremely convenient when working with cordless screwdrivers.
3. Are the drill bits suitable for hardwood?
The drill bits are optimized primarily for roughing softwood, chipboard and plywood. When drilling into extremely hard wood, caution, lower speeds and adjusted pressure are recommended to prevent the drill bit from overheating and ensure a clean cut.

• Secure the wooden workpiece firmly to the work surface.
• Mark the center of the hole and place the center tip of the drill bit at the marked location.
• Start the drill at a moderate speed and guide the bit as perpendicular to the workpiece as possible.
• Use even pressure. Do not force the drill bit into the material.
• When drilling deeper, pull the drill bit out occasionally to remove wood chips.
• Reduce pressure when passing through the other side of the wood to prevent tearing out the fibers.

• Flat drill bits are particularly suitable for quickly making larger holes in wood and wooden materials.
• For larger diameters, use lower speeds and pay special attention to tool stability.
• To make the hole come out better, you can place a piece of scrap wood under the workpiece.
• For blind holes, check the depth regularly to avoid drilling through the workpiece.
• For more precise positioning, use the center tip.
• If the drill bit jams, vibrates or overheats, reduce pressure and check the condition of the drill bit.

Warnings:
• CAUTION – rotating flat bits can cause injury and strong kickback.
