TROTEC Wood drill set (15 pieces. ), 3 to 10 mm diameter in 1 mm increments. With this 15-piece set, you have all the twist drills you need to drill into hard and soft wood or MDF boards. Even drill holes in glued or coated panels are no problem with the professional wood drill set from Trotec. As the drill bits are made entirely of durable, high-strength industrial grade carbon steel, they have very good service life even after many drilling processes. Thanks to the cylinder shaft, they can also be combined with all standard drills and cordless drills. As you would expect from a professional twist drill for wood inserts, each drill head has a precise centring tip for precise alignment, which is why no pre-graining is necessary as the drill can no longer run after attachment. An extremely sharp shoulder cutter with a maximum hardness of 58 HRC carves the wood fibres during the drilling process. The wood drill set contains all drill sizes from 3 to 10 mm diameter in 1 mm increments - up to 4 mm even multiple times. In addition, partial designs are also supplied in half millimetre increments, so that you have the right drill at hand even for less common hole sizes. The complete set is delivered in a sturdy plastic box, which allows for clean transport as well as hanging on a tool wall. All drill bits are pre-sorted to a fixed position and can be easily removed from the box due to a tilting bracket.
