Bi-Metal Hole Saw Set 6-3/8 in with Dust Bowl - Clean Cuts

In this review of the Klein Tools 80156 hole saw set, the bottom line is simple: it is aimed at electricians and remodelers who need a tidy, practical solution for cutting openings for recessed lighting. The kit's standout feature is the collapsible dust bowl that captures debris on the spot and hooks to common vacuum hoses, making drywall and ceiling work less messy. Paired with a 6-3/8 in bi-metal hole saw and a 3/8 in arbor with pins, the set is built for efficient, on-site lighting installs and quick cleanup.

Key Features

• Dust containment: The collapsible dual-material dust bowl collects debris at the cut site so installers spend less time sweeping and finishing after each hole.
• Vacuum port compatibility: The vacuum port accepts 1-1/4 in, 1-7/8 in, and 2-1/2 in hose sizes so it works with most jobsite vacuum systems for immediate cleanup.
• Large hole capability: The included 6-3/8 in bi-metal hole saw is sized to create openings for most 6 in recessed lighting fixtures, reducing the need for additional cutting tools.
• Sturdy arbor: The large 3/8 in arbor with pins provides quick engagement and disengagement of the hole saw for faster operation between cuts.
• Collapsible design: The folding dust bowl and compact components make the set portable and easy to store in a tool bag or van without taking much space.

Who It's For

This set is best for electricians, ceiling contractors, and DIYers who regularly cut drywall or ceiling tile for recessed lighting and want a neater work area. The dust bowl is especially useful on occupied jobs where minimizing dust and debris is important and where a compatible vacuum is available.

Those who primarily cut through heavy metal or make very high-volume, industrial cuts should evaluate durability expectations; while the bi-metal saw cuts steel and stainless steel as advertised, users reporting chipping or wear under intense use may prefer a heavier-duty dedicated industrial set.

Pros & Cons

Pros

• Effective dust containment keeps jobsite surfaces cleaner and reduces post-cut cleanup time.
• Versatile vacuum port fits several common hose sizes for easy connection on most vacuums.
• 6-3/8 in bi-metal saw cuts a range of materials, from drywall to thin stainless steel, and fits most 6 in recessed lights.
• Collapsible bowl and compact arbor make the kit easy to transport and store.

Cons

• Some users report mixed long-term durability, including center bit wear after repeated use, so heavy daily trade use may shorten life.
