Power drill accessory GRAPHITE 56H400 — wood drill bit, 64 mm length, 3.5 cm diameter, 1 pc

GRAPHITE 56H400 is a single-piece power drill accessory designed for drilling soft materials, primarily wood. The bit has an overall length of 64 mm and a working diameter of 3 mm (not 3.5 cm), supplied as one piece in blister packaging. It features a round holder end to fit standard drill chucks and is intended for hammerless drilling with cordless drivers and other common drills. A four-blade pilot tip and a sintered carbide blade with titanium nitride (TiN) coating provide improved durability for routine woodworking and general-purpose tasks.

Advantages

The four-blade pilot tip improves centring and stabilises the hole during drilling, reducing wandering on wood and other soft materials. Titanium nitride coating increases surface hardness and wear resistance of the sintered carbide blade, extending service life under regular use. The round holder end ensures compatibility with a wide range of standard chucks, and the blister packaging contains a single, ready-to-use drill bit for straightforward storage and handling.

Suitable for

• Drilling holes in wood for dowels, joinery and fittings
• Creating 3 mm pilot holes in plastics and soft non-ferrous materials
• General-purpose, hammerless drilling with cordless drivers

Key specifications

• Drill bit diameter: 3 mm
• Overall length: 64 mm
• Blade material: sintered carbide (SiC)
• Coating: titanium nitride (TiN)
• Tip design: 4-blade pilot drill tip for improved centring
• Holder style: round shank for standard chucks
• Packaging: single piece in blister pack

How to use

Insert the round shank of the GRAPHITE 56H400 into the drill chuck and tighten securely according to the drill manufacturer’s instructions. Use hammerless (rotation-only) mode; do not enable hammer action. Select an appropriate drill speed for wood and other soft materials—moderate speeds are typically suitable for a 3 mm bit. Apply steady, even pressure and retract occasionally to clear chips and avoid overheating. For precise locating, consider marking the spot and using a centre punch or pilot mark prior to drilling.

Usage recommendations

Use the bit only for hammerless drilling in soft materials. Avoid using excessive feed force or hammer mode to prevent damage to the TiN coating and carbide blade. Store in dry conditions and replace the bit if wear or chipping is visible to maintain hole quality and drilling safety.
