Electroformed Diamond Core Drills 0.118″-0.999″
Belgium mounted ( 1/2- Gas ) electroformed diamond core drills are drilling tools that utilize a nickel electroforming process to bond diamond particles directly to the drill body. Unlike sintered or metal bond drills, electroformed drills are electroformed in a nickel bath where diamond grit is applied resulting in a thin wall construction.
Key Features:
-
Thin-Walled Design – Produces very fine, accurate hole.
-
Sharp Cutting Action – Exposed diamond layer provides aggressive cutting with less pressure.
-
Coolant Compatibility – Typically used with water or oil-based coolant to extend tool life.
-
Nickel Matrix Bond – Electroformed nickel holds diamond crystals securely in place.
Advantages:
-
Less heat generation compared to sintered drills.
-
Can drill delicate, brittle, or hard materials without excessive chipping.
-
Excellent for small diameters and deep drilling.
Common Applications:
-
Optical materials: glass lenses, quartz, sapphire.
-
Ceramics & composites: technical ceramics, silicon carbide.
-
Semiconductor industry: silicon wafers, substrates.
-
Medical components: dental ceramics, bone implants.
-
Aerospace & electronics: advanced composites, crystals.
