The Diablo 14" x 108-Teeth Saw Blade for Thin Aluminum is a next-generation circular saw blade engineered for precise, burr-free cutting of thin aluminum (up to 1/8") as well as medium and thick aluminum profiles. Built for use on miter saws, this 14 in. blade also handles a wide range of non-ferrous metals and materials including copper, brass, plastic, and fiberglass - making it a versatile choice for fabricators and contractors who need clean, accurate results on the job site or in the shop. Made in Italy to tight tolerances, this Diablo blade pairs advanced carbide technology with noise-reducing design features for professional-grade performance cut after cut.

Key Features

• TiCo Super-Density Micro-Grain Carbide - a specially formulated carbide that withstands impact, resists wear, and delivers clog-free cuts through aluminum and other non-ferrous metals far longer than standard carbide
• Tri-Metal Shock Resistant Brazing - bonds the carbide teeth to the plate using three layers of metal for extreme impact resistance, so the blade holds up under demanding production cutting conditions
• Triple Chip Grind (TCG) Tooth Geometry - alternating tooth design that produces clean, burr-free finishes on aluminum extrusions, copper pipe, brass plate, and similar materials, virtually eliminating the need for secondary rework
• Laser-Cut Stabilizer Vents - precision-cut slots in the blade plate trap noise and dampen vibration, resulting in more accurate cuts and extended blade life over time
• Perma-SHIELD Non-Stick Coating - protective surface treatment that guards against heat buildup, gumming from soft materials, and corrosion, keeping the blade running smoothly cut after cut
• -5 deg. hook angle - negative hook geometry controls the feed rate through metal, reducing grabbing and improving safety and finish quality when cutting thin aluminum and non-ferrous stock
• 108-tooth count - high tooth count engineered for thin aluminum cutting, delivering smooth, fine finishes on sheet and extruded aluminum profiles up to 1/8" thick
• Compatible with corded and cordless miter saws - the 1" arbor and 5000 maximum RPM rating allow this blade to work with a wide range of standard miter saw platforms

Why This Product

• Designed specifically for thin aluminum cutting (up to 1/8"), the 108-tooth configuration and negative hook angle deliver the fine, burr-free cuts needed for aluminum extrusions and sheet stock without extra finishing work.
• The TiCo Super-Density Micro-Grain Carbide and Tri-Metal Shock Resistant Brazing combine to give this blade a longer service life than standard carbide metal-cutting blades, reducing downtime and blade replacement costs on production jobs.
• Versatility across non-ferrous materials - aluminum, copper, brass, plastic, and fiberglass - means one blade handles multiple material types that appear on the same job site, simplifying tool inventory.
• The Perma-SHIELD coating and Laser-Cut Stabilizer Vents work together to maintain cutting accuracy over the life of the blade by preventing heat and vibration buildup that can cause drift or premature wear.

Frequently Asked Questions

What thickness of aluminum is this blade designed to cut?

This blade is optimized for cutting thin aluminum up to 1/8" thick. The Diablo aluminum blade series also covers medium aluminum (3/32"-1/4") and thick aluminum (3/16"-7/16") in other configurations, but this 108-tooth model is specifically suited for thin aluminum stock.

Can this blade cut materials other than aluminum?

Yes. In addition to aluminum, this blade is suited for cutting copper, brass, plastic, and fiberglass. It is designed for non-ferrous metal cutting applications and should not be used on ferrous (iron-based) metals.

What is the maximum RPM for this blade, and which saws is it compatible with?

This blade is rated to a maximum of 5000 RPM and is designed for use on miter saws. It features a 1" arbor and is compatible with both corded and cordless miter saw platforms that accommodate a 14" blade.

What does the Triple Chip Grind (TCG) tooth design do?

The Triple Chip Grind tooth geometry alternates tooth profiles to distribute cutting forces evenly across the blade. This produces clean, burr-free finishes on aluminum extrusions, copper pipe, brass plate, and similar non-ferrous materials, virtually eliminating the need for secondary finishing or rework after cutting.
