The main advantages of using flat drill bits for wood

Exceptional speed and efficiency: Flat milling bits are designed to penetrate wood quickly, saving you time and energy on larger projects.
Precise centering: Each drill bit is equipped with a sharp centering point that prevents the drill bit from moving when starting to drill and ensures perfect hole positioning.
Universal use: The set covers the most popular diameters (from 10 to 25 mm), allowing you to perform a wide range of tasks with a single purchase.
Stable, non-slip grip: The hexagonal clamping (HEX handle) prevents the drill bit from rotating in the drill head, ensuring safe work even under heavy loads.

Areas of application: Where do drills work best?
The G38110 flat milling bit set is extremely versatile and suitable for a variety of woodworking projects. You can use it for:

Coarse softwood processing: Ideal for fast drilling in spruce, fir, pine and other conifers.
Drilling in wood composites: Excellent results when working with chipboard, plywood (multiplex), MDF boards and other related materials.
Installation work: Quickly creating passages for electrical cables, water pipes or threaded rods in wooden structures.

Application tip: For best results and to prevent the wood from splitting on the exit side, we recommend drilling until the centering point pierces the back of the workpiece. Then turn the workpiece over and finish drilling from the opposite side. This will give you a perfectly clean and smooth edge on both sides.

Frequently Asked Questions (FAQ) about the product
1. Are these drill bits suitable for use with a cordless screwdriver?
Yes, the drill bits have a standard hexagonal (HEX) shank, which is fully compatible with cordless screwdrivers and drills with a keyless chuck. The HEX handle prevents the drill bit from slipping, allowing safe and efficient work even with cordless tools.
2. What materials are these flat drill bits best suited for?
The drill bits are intended primarily for roughing softwood (such as spruce, pine and fir) and for drilling into chipboard, plywood and other softer wood materials. They are not suitable for metal, plastic or extremely hard exotic woods.
3. How to prevent wood from splitting when the drill bit exits?
To avoid splitting the wood on the back, drill only long enough for the centering point of the drill bit to peek through the back. Then pull out the drill bit, turn the workpiece over, and finish drilling from the other side. Alternatively, place a piece of scrap wood tightly under the workpiece.

Useful tips for work:
• Flat or spade drill bits are primarily intended for quickly drilling larger holes in wood.
• The advantage of a flat drill is rapid material removal and easy production of different hole diameters.
• Use the center tip of the drill bit for precise positioning.
• When drilling through wood, place a piece of scrap wood under the workpiece to reduce tearing on the exit side.
• For larger diameters, use lower speeds and stable pressure.
• If you want a very clean hole edge, perform the final part of the drilling slowly.
• Drill bits are not intended for drilling into concrete, stone or metal.
• After use, remove wood chips and check the condition of the cutting edges.

Warnings:
• CAUTION – rotating flat bit can cause injury and kickback.
• Always wear safety glasses.
• Always clamp the workpiece firmly and do not hold it with your hand while drilling.
• Do not remove shavings with your hands, but with a brush or other suitable tool.
• Before changing the drill bit, turn off the drill and wait until it has come to a complete stop.
• Do not use damaged, bent or badly worn drill bits.
• Keep hands, hair, jewelry and loose clothing away from rotating parts.
• Due to the larger cutting surface, there may be more kickback if the drill bit jams.
• Store drill bits in a dry place and out of the reach of children.
