LENOX Tools Hole Saw, Bi-Metal, 7/8-Inch
Brand: Lenox. Features include 2x longer life and increased wall thickness to minimize tooth loss. Optimized tooth design enhances metal penetration. This tool is best for metalworking and heavy-duty drilling where durability matters. A potential limitation is that bi-metal construction may be heavier than non-metal options.
VIKITON 7/8 Inch Hole Saw Kit
Brand: VIKITON. Includes an arbor, pilot bit, hex key, and extra replacement bit. It uses bi-metal construction with high-speed steel teeth for durability across wood, metal, plastic, and drywall. It’s lighter than some competitors, reducing operator fatigue. Limitation: may require careful alignment for optimal results on very hard metals.
Bosch HTW78 7/8 in. Edge™ Hole Saw
Brand: Bosch. This model is built for impact drivers with a durable edge and 2x life versus standard hole saws. It features BI-METAL 8-TEETH design for efficient metal cutting. Best for high-torque environments; may be less ideal for very soft materials where heat buildup isn’t a concern.
GRIXLEN 7/8″ Tungsten Carbide Tip Hole Saw
Brand: GRIXLEN. Features a 7/8″ diameter with a tungsten carbide tip and M2 pilot. The carbide tip offers strong wear resistance for metal and hard plastics. Best for hard metals; limitation is higher cost and potential rigidity in very soft materials.
DECKRKAT 2-Pack 7/8″ TCT Hole Saws
Brand: DECKRKAT. This set includes two 7/8″ TCT hole saws with pilot bits and a spring-loaded debris mechanism. Designed to cut through stainless steel, aluminum, high alloy steel, copper, plastic, FRP, and PVC. Best for heavy-duty metalwork; a cautions note is to use coolant when cutting stainless steel to extend blade life.
Buying Guide
What material will you cut most often? For metal and hard alloys, carbide-tipped or bi-metal options with robust tooth designs are preferred. For wood and drywall, standard bi-metal or tungsten carbide tips can offer faster cuts with smoother finishes.
What shank and arbor compatibility do you need? Look for a 3-flat shank or a universal 3/8″ shank and ensure your drill or CNC machine can accept it. Quick-change arbors can reduce downtime between bits.
How important is cutting speed versus longevity? Carbide-tipped bits cut faster in hard materials but may wear faster on soft plastics; bi-metal options balance speed and life. For high-torque impact drivers, choose models marketed for impact performance.
Maintenance matters. Clean chips from teeth after use and consider coolant or lubrication when drilling stainless steel to extend blade life. Replacement pilot bits and hex wrenches can save downtime.
Frequently Asked Questions
- What is a 7/8 inch hole saw best used for? – It is commonly used for metalworking, electrical, and plumbing tasks where larger openings are needed in metal, wood, and plastics.
- Are carbide-tipped hole saws worth the extra cost? – They offer greater wear resistance for hard metals but can be pricier; evaluate your frequency of use and materials.
- Can I use a 7/8″ hole saw with a regular drill? – Yes, provided the drill has adequate torque and a proper arbor/shank that fits the bit.
- Should I use coolant when cutting stainless steel? – Yes, coolant helps extend blade life and reduces heat buildup during hard-material cuts.
- Which hole saw is best for impact drivers? – Models marketed as impact-tough or Edge/HTW78 style are optimized for high-torque drivers.
- Do I need pilot bits with every hole saw? – Many sets include pilot bits; these ensure accurate centering and cleaner holes, especially in metal.
