The Minnich Dust Collection System is a powerful and easy-to-use dust collection system that can be retrofitted to any existing dowel drill unit. It uses a Venturi suction unit to remove dust from the air while drilling, and the dust is then collected in a 5-gallon pail. The system is designed to keep your work area clean and safe, and it can help to extend the life of your drill bits. Available in Single, Double and Triple configurations.
