Product information

Description

The DeWalt DT70786-QZ spiral cutting drill bit is a replacement consumable designed for general drilling applications where a spiral cutting geometry is required. Manufactured to be compatible with DeWalt compatible drill systems such as models that accept the DT70779T-QZ series, this bit serves as a spare part to restore cutting performance and maintain drilling efficiency. The tool is intended for routine drilling tasks in materials appropriate for spiral cutting geometry and fits into systems that use the matching shank and mounting configuration.

Advantages

This spiral cutting drill bit provides consistent chip evacuation due to its spiral flute design, which helps maintain cleaner holes and steady drilling progress. As a replacement part, it enables fast restoration of tool functionality without the need to replace the entire drill head. The bit is manufactured to DeWalt-compatible specifications, ensuring reliable fit and alignment with drills designed for the DT70779T-QZ family.

Suitable for

  • Routine drilling tasks in wood and similar soft-to-medium materials where spiral cutting action is appropriate
  • Replacement of worn or damaged spiral cutting bits in compatible DeWalt drill systems
  • Workshops and tradespeople requiring spare consumable bits for on-site repairs

Key specifications

  • Type: Spiral cutting drill bit
  • Application: General drilling with spiral cutting geometry
  • Compatibility: Designed for systems compatible with DT70779T-QZ series
  • Usage category: Replacement/consumable bit for drill systems

How to use

Select the DeWalt DT70786-QZ spiral cutting bit when a spiral flute profile is required for the material and task. Ensure the drill is powered off and securely clamped before replacing the bit. Insert the bit into the compatible chuck or mounting interface, tighten according to the drill manufacturer's instructions, and verify correct alignment. Begin drilling at a controlled speed suitable for the target material, applying steady pressure and allowing the spiral flutes to evacuate chips. Inspect the bit periodically for wear and replace when cutting edges become dull or flutes are damaged.

Usage recommendations

Use protective equipment such as safety glasses and gloves. Match drilling speed and feed to the material, avoid excessive side load, and replace the bit when performance decreases to maintain quality and safety.
