Adjust the drill handle position. Avoid clamping it too short to prevent bending.

Fine-tune the blade distance by removing the top nut and adding up to two washers (0.02 inches total). ?Safety Protection Measures?Shaker style router bits?Before using woodworking tools or milling cutters, always wear goggles or a transparent face shield and gloves to protect against sawdust.
