What isSDSPlus

If your doing domestic builds, small-medium shops, garden patios, sheds etc SDS+ is great. If your working on a tower-block, building a mall, shop from scratch, SDS Max. It's not just about the bit but the tool your connecting it to. An 18V set of tools are great with SDS+ for example. The battery pack you choose, if using cordless, will also have a big bearing on the quality of the end job. If buying or using corded make sure the voltage is compatible if working of a generator on site.

Materials that are highly susceptible to work hardening and strain hardening during machining are typically those with a high degree of ductility.

Understanding the nuances of work hardening aids in developing effective manufacturing strategies and maintaining the desired mechanical properties of materials.

In short, sds + is for light duty applications (drilling for ledger boards and light demo), sds max is for people who work with and demolish concrete professionally. I build decks and fences. For me sds + does everything I could ask. Good for breaking up old peirs, drilling multiple large (up to 1") holes in brick or concrete.

Distinguishing from Recrystallization: Work hardening is distinct from hot working as it occurs at temperatures below the recrystallization range. Hot working involves deformation at high temperatures, preventing strain hardening. Reversibility through Heat Treatment: Despite its transformative effects, work hardening isn't a permanent change. Heat treatment processes like annealing can restore the material's initial properties.

Increased Hardness and Strength: Work hardening increases the material's hardness and strength by reconfiguring its atomic structure, hindering further deformation. Selective Metal Susceptibility: Certain metals, such as soft, low-carbon steel, alloys containing nickel and manganese, and specific superalloys like Inconel and Monel, exhibit notable work hardening traits. Plastic Deformation as Trigger: Plastic deformation, caused by various techniques such as bending, rolling, or hammering, is the primary driver of work hardening.

Physical vapour deposition (PVD) is a thin-film coating process which produces coatings of pure metals, metallic alloys and ceramics.

Aluminium Alloys: Many aluminium alloys, such as 2024 and 7075, are highly susceptible to work hardening, requiring careful tool selection and cutting techniques. Copper and Copper Alloys: Pure copper, brass, and bronze are known for their high ductility and can 'work harden' rapidly during machining. Titanium Alloys: Titanium alloys, common in aerospace and medical applications, exhibit strong work hardening tendencies, necessitating caution during machining. Stainless Steels: Austenitic stainless steels like 304 and 316 are susceptible to work hardening. Proper tooling and cutting speeds are crucial when machining them. Nickel-Based Superalloys: Superalloys such as Inconel and Monel, used in aerospace and marine applications, are highly susceptible to work hardening. Brass and Lead: Copper-zinc alloy (brass) and soft metals like lead 'work harden' easily during machining. Certain Plastics: Thermoplastic materials like polycarbonate can exhibit strain hardening under mechanical stress during machining.

Really I would suggest using SDS Max on the larger projects where you are doing some Demo. SDS Plus is however a lot lighter and easier to move around with, as long as you dont need to go super heavy duty.

Scientific Cutting Tools (SCT) offers a range of solid carbide and carbide-tipped cutting tools for aerospace, medical, defense and job shop applications.

It's important to consider cutting parameters, tool selection, and lubrication to minimize work hardening and strain hardening effects during machining. Also, post-machining processes like annealing can relieve the hardening effects and restore the material's original properties when necessary.

It sounds like for your application, SDS Plus would be the way to go, given that they are generally less expensive, and you don't have really tough masonry work to do.

Work hardening, also known as strain hardening, is a metallurgical phenomenon observed in metals. It leads to an increase in hardness and strength due to plastic deformation below the recrystallization range. This process is primarily induced by mechanical stress, including machining and forming, causing structural changes in the material.

Basically I had to use a breaker last weekend, it was clear I did not need the “heavy duty” as I did not have 6” of solid concrete, but the descriptions of the other options confused me.

SDS Plus is an improvement on the original SDS system, but remains compatible with SDS bits, and is now the most commonly seen on the market.
