Turin™ SK40™ Single Dose Stepless Coffee Grinder
The Turin SK40 is a new stepless variation of the Turin SD40. It is a well-designed single-dose grinder that uses a tilted base and bellows to minimize retention. It is built with a sturdy aluminum body and features 40mm stainless steel conical burrs with 8 points (same as version 2 of the SD40). In contrast to other grinders within its price range, which often have higher levels of retention and plastic construction, this grinder has minimal retention and is mostly constructed with metal. We are proud to be the exclusive US importer of this product and believe it performs as well or better when compared to grinders like the Niche Zero, Breville Smart grinder, Ascaso grinders, Baratza conical grinders, Fellow grinders, and blade grinders.
It has stepless adjustment that allows for an infinite number of minute settings between the highest and lowest setting. Adjustment is made by turning an adjustment auger, that slowly turns the adjustment collar.
Comes with a wood lid, black metal hopper, black rubber bellows, and a metal dosing cup.
For those interested in the technical details, the grinder measures 6.75 inches in length, 3.75 inches in width, and 12.5 inches in height without the bellows. With the hopper, the height increases to 14 inches. It weighs 5.75 lbs and features a stainless steel dosing cup. The body and base are made of aluminum, with the hopper available in plastic or aluminum, and the bellows made of rubber. Color options for the body include white, black, and polished aluminum, with black or white bellows and polished aluminum, clear plastic, or black metal hoppers. Additionally, lids are available in wood, white, or black. The grinder runs on 110v and 60hz, with a 150-watt motor. The hopper can hold about 40 grams. During grinding the RPM is about 400 rpm. Without beans it is about 650 rpm.
The SK40 is a grinder that can be used for a range of coffee from espresso to French Press, but due to stepless adjustment, it is not as easy to switch between grind sizes when compared to the Turin SD40 V2.
Grinders are tested at the factory with coffee to ensure proper alignment, so there can be minimal signs of coffee in the burrs.
