Drill Calc vs StudPlan

Need to find the right drill bit size for a hole? Drill Calc calculates the correct drill bit size to use for threaded holes, based on the bolt (tap) diameter and thread pitch and percentage, for both inch and metric threads. Close and tight fit hole sizes for many popular drill sizes are also displayed. It also has tables of standard inch fractional and numeric drill bit sizes, as well as complete information for various pipe sizes. There is also detailed information about the commonly used sizes of wood screws. Buy your copy of Drill Calc today, and put away your drill chart.

Plan wall framing in seconds — wood or steel, straight or rake/gable — with full material takeoffs, client quotes, and cut lists ready for the job site. Built for iOS 17. No accounts. No analytics. No advertising. No tracking SDKs. 100% offline — every calculation runs on your phone, so it works in a basement or anywhere else with no signal. WHAT YOU CAN DO • FRAME A SINGLE WALL Enter length, height, and on-center spacing (12", 16", 19.2", or 24"). Choose 2x4 or 2x6 lumber. Get instant stud counts, plate lengths, board feet, wood volume, and wall area, with a live layout and your choice of end-stud configuration. Tap any field to type over it instantly. • STEEL FRAMING Cold-formed steel studs for non-load-bearing partitions — track and stud linear-foot takeoffs, gauge selection, and self-drilling screw counts. • RAKE, GABLE & ASYMMETRIC GABLE WALLS Enter a pitch (3:12 to 12:12, or custom) or low/high heights. Gable walls support a center or off-centre ridge with independent left/right slopes. Every stud comes out with its exact length and bevel angle, ready to cut. • DOORS, WINDOWS & CORNERS Drop in any opening with its rough opening size, and position it from the left edge, right edge, or center — one tap. King studs, jack studs, cripples, sills, and headers are calculated for you, including built-up trimmer posts for wide openings per IRC R602.7.5. • CUT LIST & MATERIAL TAKEOFF A full board-by-board takeoff — studs, plates, headers, blocking — per wall and across the project. Sheathing and drywall sheet counts, insulation coverage, and fastener estimates included. A buy list shows how many sticks of each market length to order, exportable as CSV. • 4×8 SHEET LAYOUT See exactly where OSB or plywood panels land on your wall. Edges on a stud are green; unsupported joins are flagged red before you start nailing. • FIXTURE BACKING Point-placed blocking for grab bars, TV mounts, and cabinets, each with its own board footage and diagram placement. • PRESETS One tap loads standard pre-cut heights (92-5/8", 104-5/8", 116-5/8"). Or save your own wall configuration once and reuse or update it on any wall. • MARK-OUT GUIDE A copy-ready list of measured positions along the plate — for marking studs on-site without re-counting. • MULTI-WALL PROJECTS Save framing jobs across multiple walls with intersection tracking (shared studs auto-deducted at T-junctions). Duplicate a wall or start the next one pre-filled with the last. Undo an accidental delete. Track totals: studs, plates, board feet, wood volume, wall area, and cost. • CLIENT QUOTE PDF & EXPORT A client-ready estimate with labor hours, material subtotal, markup, and tax — without exposing your cut list. Or export a full PDF with diagrams, cut lists, mark-out positions, and material summary. • IMPERIAL AND METRIC Feet-inches-fractions down to 1/8", or millimeters. Switch anytime without losing your project. • YOUR OWN iCLOUD SYNC Projects sync across your iPhone and iPad through your own iCloud account — optional, can be turned off in Settings. Never touches our servers; there are none. • IRC REFERENCE BUILT IN IRC R602.7 header sizing, bearing and point loads, nominal vs. actual lumber sizes, steel gauge-to-mil, common rough opening sizes, corner stud configurations, and roof pitch to angle conversions.
