Twist drill bit set Verto 60H800 — 6 pcs, lengths 230 mm, sizes 6/8/10/12/16/20 mm

The Verto 60H800 twist drill bit set includes six spiral wood drills designed for general drilling tasks with handheld drills and drill presses. Each bit measures 230 mm in total length and covers diameters of 6, 8, 10, 12, 16 and 20 mm to provide a broad range of hole sizes for construction, woodworking and light metalworking where compatible. The spiral flute geometry promotes efficient chip evacuation, including in wet wood, while the threaded tip draws the bit into the work for controlled axial feed. Hex shanks provide secure grip in chucks and quick bit changes when used with hex-capable drill chucks or adapters.

Advantages

The spiral design of these twist drill bits ensures effective removal of chips and reduced clogging during continuous drilling. The threaded point contributes to steady centring and easier penetration without excessive axial pressure. Uniform 230 mm length offers deeper drilling capacity compared with short bits, while the included range of diameters makes the set versatile for multiple tasks. Hex shanks improve retention in compatible chucks and help prevent slippage under load.

Suitable for

• Drilling holes in soft and hardwood for carpentry and furniture work
• Through-holes and dowel or bolt pilot holes in construction timber
• Drilling in wet or green wood where chip evacuation is important
• Light-duty metalworking and installation tasks when material and speed are appropriate
• Use with handheld drills and drill presses that accept hex-shank bits

Key specifications

• Set composition: six twist drill bits — diameters 6, 8, 10, 12, 16, 20 mm
• Total length of each bit: 230 mm
• Tip type: threaded point for active self-feeding and centring
• Flute: spiral geometry for chip evacuation
• Shank type: hexagonal for improved chuck retention
• Intended materials: wood (including wet wood); suitable for light-duty metal or composite materials when used appropriately

How to use

Select the drill bit with the required diameter and insert the hex shank securely into the drill chuck or hex adapter. Clamp the workpiece as needed and mark the drilling position. Start drilling at low speed to allow the threaded tip to engage and self-feed, then increase speed and apply steady pressure appropriate to the material. Withdraw the bit periodically on deep holes to clear chips and avoid overheating. After use, clean chips from the spiral flutes and store bits in a dry place to prevent corrosion.

Usage recommendations

Use cutting speeds and feed rates suited to the material: lower speeds for large diameters and hardwood, moderate speeds for softwood. Apply even pressure without forcing the bit; let the threaded tip guide the feed. For prolonged durability, keep bits clean and dry, and avoid using wood-specific bits on hard metals except for light-duty tasks.
