Janka, Board Feet & Drill Bits
Only for iPhone
$9.99
iPhone
Woodworker's Toolbox puts the calculations and reference charts you actually need right next to your workbench.
Fraction Calculator
Do math the way woodworkers think — in fractions. Add, subtract, multiply, and divide without touching a decimal. Quick-tap shortcuts for common sizes like 1/8 and 1/16. See results as fractions, decimals, or metric.
Board Feet Calculator
Figure out how much lumber you need and what it'll cost. Enter dimensions in fractions or decimals, add a price per board foot, and you're done.
Drill Bit Selector
Tell it the hole size you need, and it finds the closest standard bit — fractional, wire gauge, or letter. Always rounds up so your hardware actually fits.
Janka Hardness Chart
Compare wood hardness before you buy. Over 900 species ranked by Janka rating — from soft pine to Brazilian walnut. Filter by hardness range to find the right wood for flooring, furniture, or any project where durability matters.
Wood Movement Calculator
Plan for wood movement before you build. Enter species, moisture content change, and board dimensions to get predicted shrinkage and expansion across the grain. Prevents warping, cupping, and joint failures before they happen.
Wood Species Database
Reference data for hundreds of species: Janka hardness, shrinkage values, common uses, and workability notes. Know your material before you mill it.
Built for the shop: large buttons, one-handed use, no account, no data collected.
Adds Wood Movement Calculator and Janka Hardness Chart with 900+ species
