HW Solide carbide dowel drills for through holes

A dowel drill for through holes, also known as a through drill, is a drill with a centering point and two sharp cutting edges on the outside. These cutting edges ensure that the drill enters and exits the wood cleanly, without splinters or breakout on the underside.

What is a dowel drill for through holes used for

Dowel drills for through holes are used for making holes that pass completely through the workpiece. A dowel drill for through holes can create holes on both sides of the material, making them suitable for applications that require a hole to go all the way through a workpiece.

A dowel drill for through holes can be used in CNC milling machines, line drilling machines, and other tools to create blind holes in solid wood, composite wood, and laminated panel materials. The main applications and functions of dowel drills for through holes are:

• Creating Through-Holes: Dowel drills for through holes are used when a hole is needed that passes from one side of the material to the other. This is often required for assembly, fastening, or when a continuous passage is needed.

• Creating Fastening Points: A dowel drill is commonly used to create points where bolts or screws can pass through to fasten two parts of the workpiece together.

• Creating Dowel and Hole Joints: In woodworking, dowel drills for through holes are often used to create dowel joints, where dowels are inserted into holes to form strong, durable connections.

• Hinge Installation: When installing hinges in doors, cabinets, or other structures, a dowel drill for through holes is useful for making holes for the screws that secure the hinge in place.

Benefits of dowel drills for through holes

Dowel drills for through holes stand out from standard spiral drills due to their unique design. They have a long, slim shaft and a relatively small cutting head with a sharp point and often two cutting edges. This design is optimized for the following:

• Straight Holes: The length of the drill provides stability and guidance, significantly reducing the risk of the drill "wandering." This is crucial for drilling long, straight holes, such as for passing shafts, cables, or other components through.

• Clean, Splinter-Free Drilling: The sharp cutting edges and point of the drill ensure a clean cut, minimizing the risk of splintering the wood at the entry and exit points of the hole. This is especially important when working with delicate wood types or when an aesthetically pleasing result is required.

• Efficient Chip Removal: While the design may seem less efficient than a spiral drill for rapid chip removal, dowel drills for through holes are often equipped with special grooves or a polished surface to facilitate wood chip removal, especially in deep holes.

• Specifically for Screws: The diameter of dowel drills for through holes is often matched to common screw diameters, making them ideal for pre-drilling holes for screws, which eases the screwing process and further reduces the risk of wood splitting.

Tips for using a dowel drill for through holes

To get the most out of your dowel drills for through holes and ensure the best results, it's important to follow some guidelines:

• Choose the Right Diameter: Make sure the diameter of the drill matches the screw or object that will pass through the hole. For screws, it's often recommended to choose a drill slightly smaller than the core diameter of the screw thread.

• Use a Drill Stand or Column Drill: For the most straight and precise holes, it’s recommended to use a drill stand or column drill. This minimizes the chance of deviation.

• Keep the Drill Clean and Sharp: A dull drill will cause more friction, burn the wood, and increase the risk of splintering. Clean your drills regularly and have them sharpened when necessary.

• Apply Proper Pressure: Let the drill do the work. Apply consistent, moderate pressure and do not force the drill through the wood. Too much pressure can lead to overheating and damage to the drill or the workpiece.

• Remove Chips Regularly: Especially with deep holes, it’s important to occasionally retract the drill to clear the chips. This prevents the drill from jamming and reduces heat buildup.

• Use a Test Piece: Before drilling into your final workpiece, it’s always a good idea to drill a test hole in a piece of scrap wood of the same type. This gives you an idea of how the drill behaves and whether the diameter is correct.
