Description
Note: The reamer needs to be operated at the "slowest speed". Drilling too fast will cause uneven gravity distribution and vibration, resulting in a larger hole.
Specifications:
Product: HONGDUI Hooked On Wood Precision Workbench Grid Layout System 20mm Forstner Main Boring Guide With Dust Port 3mm Pilot Guide Stop Collar
Dog hole diameter: 20 mm
Pilot hole size: 3 mm (pilot drill bit required, not included)
Template system: Repositionable for continuous grid layout

Suitable worktops: Wood and wood-based bench tops
Features:
1. Precision grid system: Template and guides deliver consistent 20 mm spacing and alignment for professional bench performance.
2. Clean, accurate bores: Forstner bit and stabilized boring guide reduce tear-out while the dust port clears chips for better visibility.
3. Exact depth every time: Stop collar sets repeatable drilling depth to avoid blowout and over-drilling.
4. Secure, repeatable setup: Screw-down caps and anchor rings lock the template; the 3 mm pilot guide prevents wandering.
5. Scalable workflow: Drill pilots, bore dog holes, shift the template, and continue the grid; optimized for 6 bench dogs (min 4).
