GRAFF 8% Cobalt Premium Hacksaw Blades
Product overview: These 12-inch hacksaw blades are designed for stainless steel and metal cutting with enhanced durability from an 8% cobalt content. The small tooth pitch helps resist abrasion, while the bi-metal construction maintains working qualities under bending stresses. Ideal for fast, precise cuts in metal and steel, including stainless applications.
Two Replacement Stainless Steel Blades
Product overview: This set includes two stainless steel blades with a total length of 12.5 inches and 10.3 inches of cutting teeth. Stainless construction offers resistance to rust and corrosion, suitable for extended use in metal-cutting tasks that involve stainless steel or other metals.
JUGREAT 12″ Bi-Metal Blades
Product overview: A 12-inch, 32 TPI bi-metal blade designed for high-speed cutting with a flexible steel body. The D6A M2 material provides durability and resistance to fatigue, suitable for cutting metals such as stainless steel, rebar, and various metal profiles. Pack size: 10 blades.
JUGREAT 10″ Bi-Metal Blades
Product overview: This 10-inch bi-metal blade uses 32 TPI for precise metal cuts and high-speed performance. The 0.025″ thickness and 1/2″ width support a robust cutting edge, making it suitable for stainless steel and other metals commonly encountered in plumbing, electrical, and construction work. Pack size: 10 blades.
Hacksaw Replacement Blades (10 Pack) 24 TPI
Product overview: This 12-inch blade set features 24 TPI bi-metal blades with wavy teeth designed for versatile material cutting, including steel and piping. The high-speed steel teeth offer efficient metal cutting, while the blade’s flex and endurance support use in restricted or interrupted cuts.
Starrett Bi-Metal Safe-Flex
Product overview: Starrett’s patented diffusion-processed bi-metal blade offers high durability and reduced tooth breakage in challenging cuts. It excels in cramped or interrupted cuts and bending-stress scenarios, delivering reliable performance for stainless steel and tough metals.
Buying Guide
Key considerations when selecting hacksaw blades for stainless steel and metal cutting include blade material, tooth geometry, and blade length. Bi-metal blades blend flexible spring steel with high-speed steel teeth for durability and faster cutting through metals. For stainless steel, lower tooth pitch (fewer teeth per inch) often requires tougher teeth and cobalt enhancement to resist wear. A higher TPI (teeth per inch) provides smoother cuts but may slow aggressive metal removal; lower TPI blades cut quicker but produce rougher edges.
Consider blade thickness and width: typical 0.025-inch thickness and 1/2-inch width offer a balance of rigidity and control for most standard hacksaw frames. When cutting stainless steel or harder metals, cobalt-reinforced blades (around 8% cobalt) can extend blade life. For tight or irregular spaces, Safe-Flex or high-tension blades help maintain straight cuts with reduced blade twist.
Maintenance and usage tips: ensure proper tension on the hacksaw frame, apply steady feed pressure, and use cutting fluid or light oil to reduce heat and wear. If blades exhibit visible teeth wear or bending, replace promptly to avoid uneven cuts or blade breakage. When choosing between options, factor in your typical material types, work environment, and the need for spare blades to minimize downtime.
