The Mafell 090221 is an extreme-capacity 30mm diameter Lewis pattern auger bit engineered exclusively for the Mafell ZB 600 E Carpenter's Wood Drill. Offering an 820mm overall length and a massive drilling depth of 475mm, it is purpose-built to bore wide, accurate holes entirely through oversized timbers, glulam, and heavy structural beams.

Featuring a traditional Lewis flute geometry, this bit aggressively pulls large wood chips and heavy shavings out of the deep bore path to prevent tool binding and heat buildup. Its robust shank design integrates directly with the heavy-duty ZB 600 E toolholder, guaranteeing secure torque delivery and strict alignment during extreme timber framing applications.

Features & Benefits

• Lewis Pattern Flute: Delivers continuous, high-volume chip extraction to maintain cutting speed and prevent clogging in deep bores.
• Exact Compatibility: Precision-machined shank ensures secure toolholding and handles the high torque of the Mafell ZB 600 E.
• Extreme Capacity: 475mm maximum drilling depth enables single-pass boring through extra-thick architectural timbers and logs.
• Heavy-Duty Construction: Minimizes bit deflection to yield straight, accurate holes in heavy timber framing and log building.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery. We use USPS, which typically takes 2-8 days for delivery, depending on your location, for smaller items and UPS Ground for all other ground shipments under 150 pounds.

• Returns: We accept returns and exchanges for a fee up to 30 days in unopened, new, and unused condition in the original packaging. Exceptions apply.

Please note, NO REFUNDS will be given on any new, used, or damaged item if it is not returned in the original packaging, no matter what condition the packaging is in. If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.
