Core Drill Bits in Altadena, CA
Looking for professional core drill bits in Altadena, CA? Diamond saw blades and bits are high-precision abrasive tools featuring synthetic diamond segments embedded along a high-strength alloy steel core. Designed for heavy masonry saws, cut-off saws, and walk-behind road equipment, these tools utilize sintered bond metallurgy to grind away aggregates cleanly. Matching aggregate hardness to matrix bond is critical to prevent segment glazing. For broad technical specifications, view our national catalog for core drill bits.
Hollow Tube design & Sintered Segments
Bond & Aggregate Adaptation
Boring deep openings in reinforced concrete requires a tool that minimizes surface contact area to maintain drilling torque. The hollow steel tube design allows the bit to grind only the outer perimeter of the hole, leaving a solid core plug that is extracted afterward. The segmented teeth feature high concentrations of industrial synthetic diamonds bonded in a soft cobalt-iron alloy matrix, allowing the bit to slice through embedded steel rebar without binding, utilizing sintered bonds similar to our premium concrete cutting blades.
Geological Reality: Historic clay brick structural masonry, natural granite stone slabs, and decorative sandstone. We recommend our specialized soft bond masonry blades or tuck-pointing diamond blades for mortar joint repair.
Operational Parameters
Wet core bits utilize continuous water flow inside the tube to cool the segments, flush out concrete slurry, and suppress silica dust. Dry core bits feature laser-welded segments and are designed for drilling softer brick, block, and non-reinforced concrete walls where water cannot be introduced.

Local Contractor FAQ
Direct, high-density technical answers for Altadena projects.
How does a diamond core bit handle structural steel rebar?
The high concentration of diamonds in the segments grinds through the steel rebar. When the bit hits rebar, the operator must slightly reduce feed pressure and let the diamonds grind through the steel without forcing the drill.
What is the difference between wet and dry core bits?
Wet bits require constant water feed to flush out slurry and cool the segments in hard reinforced Core Drill Bits. Dry bits are used on handheld rotary drills to bore dry holes in brick, block, or soft masonry.
How do you extract a stuck Core Drill Bits core plug?
If the Core Drill Bits core plug is wedged inside the tube, tap the steel side of the barrel gently with a wooden block or slide a rod through the threaded arbor end to push the core plug out.
