Concrete Core Drill Calculator
Diamond Coring Hole Templates
$1.99 · Designed for iPad. Not verified for macOS.
Concrete Core Drilling brings two professional-grade angle calculators to your iPhone and iPad. Built for core drilling contractors, masons, plumbers, HVAC technicians, electricians, and serious DIYers who need exact geometry before the diamond bit touches concrete.
TWO CALCULATORS
▷ Floor AND Wall — angled core through a floor that exits the outer face of an adjacent wall. Enter hole diameter, floor and wall thickness, and inside-wall-to-hole-center. Pick a target Center Drop OR Drill Angle and the app instantly solves for the other, plus: center drill length, max drill length, floor crossing length, wall crossing length, and the elliptical hole footprints on both surfaces.
▷ Floor OR Wall — angled hole through a single concrete slab or wall. Get the hole offset, full drill length, and surface hole width in one tap.
PRECISION YOU CAN TRUST
• Metric (mm) and imperial (whole inches + 1/16″ fractions)
• Live cross-section diagram with pinch-to-zoom and pan
• Full-scale ellipse hole templates for floor and wall
• Drill angle slider for quick what-if analysis
• Accepts dot AND comma as decimal separator — works in any locale
TAKE IT TO THE JOBSITE
• Export to PDF: inputs, results, cross-section diagram, and full-scale templates on dedicated pages
• Export quick text summary for SMS, email, or job notes
• Save and reload unlimited named projects
• Built-in core bit reference: 25 mm to 600 mm / 1″ to 24″ with typical applications (conduit, drainage, HVAC, anchors, access openings, tunnels)
DESIGNED FOR PROFESSIONALS
Routing a sewer line through a basement wall. Installing HVAC ductwork. Drilling rebar anchors. Coring conduit channels. Planning a tricky angled penetration. This app delivers the math in seconds — visualized, exportable, and ready for the rig. Native iOS app: fast, fully offline, no ads, no accounts.
STAY SAFE
Silica dust is invisible — and irreversible. The app includes a built-in reminder to always cut wet and wear proper PPE.
Concrete Core Drilling — geometry done right. Stop guessing. Start drilling.
