Hey woodturners and pen makers, this WoodRiver 14mm pen maker's bit is exactly what you need for clean, precise holes in your pen blanks. Made from high-speed steel, these bits are specifically designed for pen making with precision grinding that starts cleanly and limits exit hole chip-out - meaning fewer ruined blanks and less frustration. The deep smooth flutes provide superior chip extraction, which is crucial when drilling through various wood types and acrylics. The extra sharp lands and flutes give you precision-sized holes that match pen kit components perfectly. For bits with shanks 31/64 inch and 11mm or larger, they've reduced the shank to 7/16 inch for better compatibility with various chucks. WoodRiver really understands what pen makers need - these bits are all about reducing wasted materials and giving you consistent, professional results. Whether you're new to pen turning or you've been at it for years, having quality bits specifically designed for this purpose makes a huge difference in your finished products. The 14mm size is perfect for many popular pen kits, and the quality is evident from the first use. Seriously, if you're tired of bits that wander or cause tear-out, this is the solution you've been looking for.
