Recommended starting set for mixed demolition work
LENOX 1214412RKD: choose it for a useful wood-and-metal blade mix
Start with the LENOX 1214412RKD 12-piece demolition set when your projects involve nail-embedded lumber and a mix of metal rough cuts. It combines six- and nine-inch blades with several tooth counts, so the purchase is a selection of tools for different cuts rather than one “universal” blade.
If you repeatedly cut only one material, a pack of the appropriate individual blade may be a better use of the budget. Verify the marked blade and material range before cutting; the set is not a substitute for specialized blades where the job requires them.
The blade makes contact with the material, so choosing it carefully can matter more than buying a more powerful saw. This guide focuses on a verifiable LENOX demolition set and explains how to select from its contents, when to buy individual replacements, and how to recognize a blade that needs retiring.
The manufacturer continues to list the 1214412RKD, and its exact Amazon US offer was available new on October 12, 2026. This is a researched buying guide. We have not conducted a blade-life or cutting-speed test, and we do not turn manufacturer life claims into guarantees for your project.

The manufacturer identifies the component models as 6066R, 6114R, 9114R, 966R and 960R, with a storage case. Check the exact delivered markings and seller contents. A six-inch and nine-inch blade with the same tooth count differ in reach and flexibility; choose length for the whole cut, including the saw’s stroke.
Choose the material before choosing the tooth count
Nail-embedded lumber
Choose a blade explicitly intended for wood with embedded fasteners. Inspect the work for nails and screws even when it looks like ordinary lumber. A demolition blade is a more relevant starting point than treating every clean-wood blade as suitable for metal. Support the piece and its offcut so the blade is not pinched.
Metal and pipe
Match the blade to the metal type and wall thickness. Thin tubing and a thick solid section are different demands. Use the maker’s application range, and keep enough teeth engaged according to the blade guidance. A larger tooth count is not automatically the best choice for every metal cut.
Special materials
Cast iron, abrasive masonry, tile, stainless steel and other demanding materials can require a specialized blade. Check the explicit application before using one of this set’s blades. A mixed demolition kit does not establish suitability for every material a reciprocating saw can reach.
Why this set can be useful for renovation
The 1214412RKD provides several blade choices in a case. That is useful when dismantling material exposes a mixture of wood and metal, or when the same project includes different cutting depths. The value lies in having an appropriate choice ready rather than forcing one blade through every task.
The set does not make material identification unnecessary. Stop when the work changes, inspect what you are about to cut and select the appropriate blade. If an opening reveals a pipe or cable, that is a reason to reassess the operation, not simply switch to a metal blade. Hidden services, structural members and loaded material need deliberate planning before cutting.
Bi-metal construction and marketing life claims
LENOX describes a high-speed-steel cutting edge with spring-steel backing for this demolition kit. Its taller, thicker profiles are intended to add durability for rough work. That construction is a reason to compare the set for demolition, not proof that a blade cannot bend or lose teeth.
Do not convert a manufacturer comparison such as an “up to” life claim into a promise of twice as many cuts in your work. Material, embedded fasteners, blade temperature, support and technique all influence blade life. The useful purchase question is whether the blade is appropriate for the recurring task and can be replaced economically when worn.
Length: enough reach without unnecessary flex
Select a blade that remains beyond the material through the full stroke. Too little reach can make the tip catch inside the work. More length than the job needs can leave a flexible tip extending into obstacles or make a cut harder to control. Measure the work and check the saw’s instructions before choosing between the six- and nine-inch groups.
A longer blade can solve a real depth requirement, but it is not a substitute for a clear cutting path. Check what is behind and beneath the work. Support the stock and keep the shoe in appropriate contact as instructed. If you cannot establish safe clearance, change the setup rather than relying on the blade to bend around the problem.
Tooth count is one part of the decision
TPI means teeth per inch. Coarser spacing generally provides larger spaces for chips, while finer spacing gives more teeth over a short contact length. The correct choice still depends on the material, thickness and blade geometry. Use the marked application and the maker’s guidance instead of a rule that says one tooth count cuts everything.
A 14-TPI blade and a 6-TPI blade should not be selected solely by which is nearest in the case. For mixed work, pause and identify the next material. For repeated production-like cuts in one material, choose the proper individual blade and track replacement needs rather than repeatedly buying a mixed set whose other pieces remain unused.
Buy the set or replenish individual blades?
Buy the set when you expect to use several of its blade groups and the case helps keep them organized. Buy an individual pack when one verified blade repeatedly does the work and you rarely need the rest. Compare the number of useful blades rather than dividing the package price by every piece and calling the lowest number the best value.
Keep the exact model of a blade that suits your task. A brand name alone is not enough to reorder the same geometry, length and tooth count. Check whether an offer is a single blade, multipack or mixed assortment, and distinguish new from used or open-box contents. Package titles and photos can be incomplete; the delivered markings should match the promised item.
Setup and care that help the blade do its job
Remove the battery or disconnect the cord as the saw manual requires before fitting a blade. Inspect the shank and clamp, seat the blade fully and confirm retention. Wear appropriate protection, clamp loose stock, and plan support for the offcut. Start at a suitable speed and let the blade cut rather than using excessive pressure.
After a cut, allow a hot blade to cool before handling. Clean and store blades using the manufacturer’s guidance, protect the teeth from other tools and separate damaged pieces from usable ones. Do not straighten a badly bent blade and assume it is restored. Missing teeth, cracks, damage at the shank and noticeably poorer progress are reasons to inspect and replace it.
If a blade dulls unusually quickly, reassess the material match, support, speed and pressure. For metal, use only lubrication appropriate to the blade, material and tool instructions. Maintenance cannot turn an unsuitable blade into the correct one, and forcing a worn blade is not an economical alternative to replacement.
LENOX blade buying questions
Is this a universal set for every material?
No. Choose each blade for its marked application and the actual material thickness. Specialized materials may need a different blade.
Does 12 pieces include the case?
The listed mix totals twelve blades; the manufacturer also identifies a storage case. Verify the exact offer and delivered contents.
Will these fit my reciprocating saw?
Check the blade shank and saw clamp compatibility in the exact tool manual. A brand name or “Sawzall” description alone is not a complete compatibility check.
Should I use the longest blade available?
Use enough length for the full stroke and cut, with adequate clearance. Unneeded length can add flex and expose the tip to obstacles.
Are these fine-finish woodworking blades?
This is a demolition-oriented set. Choose an appropriate tool and blade for a visible precision edge or fitted joint.
How long will a blade last?
No fixed cut count is promised. Material, fasteners, support, technique and blade condition all affect life.
The buying decision: a mixed set for mixed work
The 1214412RKD is a useful LENOX starting point for suitable wood-and-metal demolition tasks. Buy it because the mix fits the project, then choose deliberately from the case. For repeated cuts in one material, replenish the exact individual blade that works for that task.
