6 Best Hole Saws for Lockset Preparation That Last
Tired of dull tools? Discover the 6 best hole saws for lockset preparation that provide clean cuts and long-lasting durability. Upgrade your toolkit today.
Installing a lockset correctly is the difference between a secure, weather-tight door and a headache that persists for years. If a hole is drilled poorly, the latch alignment suffers, or worse, the surrounding wood fibers tear, compromising the structural integrity of the door stile. Getting the job done right requires the right cutter, the right speed, and a steady hand. Here are the best hole saws on the market for ensuring professional, lasting results.

Diablo 14-Piece Hole Saw Kit: Best Overall
Diablo consistently hits the sweet spot for performance and longevity in varied site conditions. These saws utilize a specialized carbide-tipped design that maintains its edge significantly longer than standard bi-metal alternatives, especially when encountering dense hardwoods or reinforced entry doors.
The tooth geometry is optimized to prevent clogging, which keeps the tool cool during heavy-duty cutting. For a contractor moving between high-end residential custom builds and repair work, this consistency is invaluable. The kit provides a comprehensive range of sizes, ensuring every standard lockset diameter is covered without needing auxiliary bits.
The bottom line: Invest in this kit if versatility and long-term durability are the priorities. It handles the widest variety of door materials with minimal effort.
Milwaukee Hole Dozer Kit: Toughest on the Job
When a project demands raw strength, the Milwaukee Hole Dozer is the standard. These saws are built to withstand the abuse of a busy job site, featuring a reinforced steel backing and a proprietary tooth design that resists stripping even when hitting hidden fasteners or metal backing.
They excel in heavy-traffic environments where speed and resilience are tested daily. The deep-cut design allows for drilling through thick exterior doors with ease, while the plug ejection slot is angled to make clearing debris a quick, one-handed task. This is a tool designed to take a beating and keep cutting straight.
The bottom line: Choose the Hole Dozer when working in environments where tools are frequently dropped or pushed to their limit. It is essentially indestructible under normal operating conditions.
LENOX Speed Slot Kit: Best for Pro Installers
Professional installers favor LENOX for the patented “Speed Slot” design, which uses a stepped geometry to facilitate easy plug removal. Anyone who has spent time prying wood chunks out of a hole saw knows exactly how much time is lost during a multi-door installation project.
Beyond the speed of clearing, these saws feature high-speed steel teeth welded to a durable alloy body. This construction provides excellent control, which is vital when you are drilling pilot holes through pre-finished veneer doors where zero margin for error exists. Precise control often determines whether a door frame stays clean or gets mangled.
The bottom line: If a high volume of installations is the daily norm, the efficiency gains from the Speed Slot system pay for the kit within a few jobs.
Bosch Daredevil Carbide Kit: Fastest Cutting
The Bosch Daredevil line is engineered for speed, specifically catering to the need for rapid progress on a tight construction schedule. The carbide teeth are aggressive and stay sharp through repeated high-speed applications, significantly reducing the “dwell time” that usually causes heat build-up and wood scorching.
Fast cutting isn’t just about speed; it is about reducing the friction that leads to burnt wood and dull teeth. When you need to prep a dozen doors in a single afternoon, the heat dissipation properties of these saws prevent the blade from softening or warping under pressure. They are precision tools that cut through solid-core and steel-clad doors with aggressive efficiency.
The bottom line: Go with the Bosch Daredevil if the project timeline is tight and high-speed, accurate cutting is the primary requirement.
Spyder TCT Hole Saw Kit: Best Quick-Change System
Spyder revolutionized the user experience with its proprietary arbor system that allows for tool-free, instant blade changes. Transitioning between a 2-1/8 inch lock hole and smaller diameter bores becomes a seamless movement, which is critical when navigating various hardware configurations on the same job site.
The Tungsten Carbide Tipped (TCT) teeth provide an exceptionally clean entry and exit point. A clean cut is non-negotiable for high-end trim work, where tear-out is essentially a failure. The Spyder system minimizes vibrations, ensuring that the drill remains stable even at the exact moment of breakthrough.
The bottom line: Select the Spyder system if ease of use and rapid transitions between different hole sizes are required.
DeWalt Bi-Metal Hole Saw Kit: Great Value Pick
DeWalt provides a reliable, bi-metal option that performs well above its price point for the average user or the homeowner tackling a home renovation. While bi-metal saws eventually dull faster than carbide, this kit offers a dependable, rugged construction that handles standard softwood and composite doors without complaint.
The set includes a high-quality arbor and pilot bits that track straight, preventing the “wobble” that leads to over-sized or off-center holes. It is a workhorse set that covers the essentials without the premium price of high-end industrial carbide kits. For the occasional project or shop use, it delivers reliable professional results.
The bottom line: The DeWalt kit is the best choice for DIYers or contractors who want professional-grade reliability without a major upfront investment.
Key Hole Saw Sizes You Need for Standard Locksets
- 2-1/8 inch (54mm): The industry standard for the main deadbolt or entry knob bore.
- 1 inch (25mm): Used for drilling the edge bore to accommodate the latch bolt.
- 1-1/2 inch (38mm): Occasionally required for specific decorative or high-security locksets.
Always verify the manufacturer’s template before cutting, as some custom hardware sets require unique clearances. Having a set that includes the 2-1/8 inch and 1 inch bits is mandatory for any standard door prep.
Carbide vs. Bi-Metal: Which One to Choose?
Carbide-tipped hole saws are the superior choice for high-volume work and cutting through difficult materials like reinforced steel or dense composite doors. They retain their sharpness significantly longer and produce less heat, reducing the risk of charring the wood.
Bi-metal hole saws are constructed from hardened high-speed steel, making them flexible and resistant to shattering under impact. They are excellent for softer woods and general residential doors where budget is a factor. Choose carbide for longevity and performance; choose bi-metal for affordability and impact resistance.
Pro Tips for Drilling Clean Holes Without Tear-Out
- Use a sacrificial backer board: Clamp a scrap piece of wood to the back of the door to support the fibers as the bit exits.
- The half-way rule: Drill from one side until the pilot bit breaks through, then finish the hole from the opposite side.
- Control the speed: Keep the drill speed moderate; excessive speed creates heat, which glazes the wood and dulls the teeth rapidly.
- Clear the chips: Frequently back the saw out of the cut to eject wood chips, which prevents friction build-up and keeps the cut cool.
How to Make Your Hole Saws Last Season After Season
Clean your saws immediately after use to prevent resin and sap buildup from hardening on the teeth. If the saws get clogged, use a specialized resin remover or a stiff wire brush to clear the gullets.
Always store your hole saws in their original case or a dedicated organizer to prevent the carbide or steel teeth from banging against each other. Finally, never force a dull saw; it will only overheat the metal and ruin the temper of the steel. Replacing or sharpening a bit when it starts to drag is much cheaper than replacing a ruined door.
Choosing the right hole saw isn’t just about the initial purchase; it’s about having a tool that respects the material you are working on. By selecting the right gear for the specific application and following basic maintenance protocols, you ensure that every door prep is accurate, clean, and built to last.
