Relton (HST-16) Tub, Tile and Spa Cutter 1" Brazed-Carbide Hole Saw Drill Bit
Tub, Tile and Spa Cutter 1" Brazed-Carbide Hole Saw
Precision drilling through ceramic, stone, and composite materials with industrial-grade carbide construction
The Relton HST-16 delivers clean, precise 1-inch diameter holes through tile, tub, and spa materials without cracking or chipping. Built with brazed-carbide construction and a 2-inch drilling depth, this hole saw handles everything from delicate ceramic tile to dense granite and composite gelcoat with consistent performance.
Engineered for Hard Surface Drilling
Brazed-Carbide Edge
Industrial carbide tips brazed directly to the steel body for maximum heat resistance and cutting longevity through abrasive materials
1" Diameter Cut
Standard one-inch bore size ideal for plumbing penetrations, shower valve installations, and spa jet fittings
Carbide-Tipped Pilot
Integrated pilot bit with carbide tip ensures precise centering and prevents wandering on hard, glazed surfaces
2" Drilling Depth
Standard depth accommodates most tile and substrate combinations without requiring multiple passes or extended arbors
Complete Assembly
Includes hole saw cutter-head, shank, and carbide-tipped pilot—ready to mount on standard drills with no additional components
Multi-Material Design
Engineered to cut ceramic, porcelain, natural stone, engineered composites, and fiberglass without specialized bits
Approved Materials
The Relton HST-16 1-inch hole saw is designed for professional and residential drilling applications through ceramic tile, marble, granite, Corian solid surface, gelcoat, and fiberglass. Suitable for tub and shower installations, spa jet penetrations, tile backsplashes, vanity plumbing, and any hard surface requiring clean, round penetrations. Compatible with standard electric and cordless drills with variable speed control.
Relton has manufactured precision drilling tools for trade professionals since 1959, trusted across plumbing, tile, and remodeling industries.
