Spade drill bit Irwin 10507905, 6 mm, single piece

Irwin spade drill bit 10507905 with a 6 mm cutting diameter is a single-piece flat-blade bit intended for drilling through wood and similar soft materials. The spade-style design creates fast, clean bores in timber, chipboard and panels and is compatible with standard rotary drills for general woodworking tasks such as installing cables, making pilot holes and producing through-holes.

Advantages

The single-piece construction provides rigidity and straightforward handling during use. The 6 mm diameter offers a common size for pilot holes and cable passages while the spade profile removes material quickly, reducing drilling time in soft substrates. Designed for rotary drilling, the bit delivers consistent bore shapes when used at low speeds and with appropriate cooling.

Suitable for

• Drilling through timber, chipboard and plywood
• Creating pilot holes for screws and fasteners
• Making cable and conduit entry holes in wooden panels
• Fast through-holes in general woodworking and carpentry

Key specifications

• Type: spade (flat) drill bit
• Diameter: 6 mm cutting edge
• Material compatibility: suitable for soft materials such as wood and panel materials
• Shank type: straight shank compatible with standard drill chucks
• Quantity: 1 piece

How to use

Secure the spade bit in a standard drill chuck and set the drill to rotary mode only; do not use hammer action. Use low rotational speed—around 300 RPM is recommended—to reduce splintering and improve control. Apply steady, moderate pressure and let the bit cut without forcing. For longer or deeper holes, withdraw the bit periodically to clear chips and prevent clogging. If drilling near finished surfaces, clamp the workpiece and support the exit side to minimise tear-out.

Usage recommendations

Use water cooling where practical to reduce heat when drilling prolonged holes, and avoid hammering or impact modes. Although the spade profile is primarily for wood and similar soft substrates, rotary-only drilling with appropriate speed and cooling is advised when working with harder or brittle materials.
