Twist wood drill bit set MODECO MN-61-571 — cylindrical spiral bits 4, 5, 6, 8, 10 mm

Set of MODECO MN-61-571 spiral twist drill bits designed for drilling wood. This kit includes five cylindrical shank bits with diameters 4, 5, 6, 8 and 10 mm. Each bit has a standard spiral flute geometry to evacuate chips efficiently and produce clean through holes and pilot holes in soft and hard wood. The cylindrical shanks fit common handheld drills and drill presses, making the set suitable for general carpentry, joinery and installation tasks.

Advantages

The twist wood drill bit set offers a compact selection of commonly used diameters that cover most woodworking needs. Standard spiral flutes provide consistent chip removal and reduce clogging during continuous drilling. Cylindrical shanks ensure compatibility with standard chucks and allow quick bit changes between handheld and stationary drilling equipment. The variety of diameters enables precise selection for dowels, pilot holes for screws and through-holes for fittings.

Suitable for

• Drilling pilot holes for wood screws
• Creating through-holes for dowels and fasteners
• General carpentry and joinery tasks
• Installation work with handheld drills or drill presses

Key specifications

• Material: high-speed steel (typical for twist bits; designed for wood drilling)
• Shank type: cylindrical (round)
• Flute type: standard spiral for chip evacuation
• Included diameters: 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Intended use: wood drilling (soft and hard wood)
• Compatibility: handheld drills and drill presses with standard chucks

How to use

Secure the selected bit in the drill chuck and tighten it firmly. Mark the drilling location on the workpiece and, if needed, clamp the workpiece to prevent movement. Start drilling at low speed to create a centered entry, then increase speed as the bit advances, applying steady, moderate pressure. Clear accumulated chips periodically by withdrawing the bit slightly during drilling. For through-holes, reduce speed when exiting the material to minimize splintering at the exit side.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Match drill speed to the wood type: lower speeds for hard wood and higher speeds for soft wood. For accurate results, pilot smaller diameter holes before enlarging to final size. Store bits in a dry place to avoid corrosion and check bits for wear before use.
