TohnichiAdjustable Torque Screwdriver RTD120CN 20~120 cNm

I needed a torque screwdriver to apply the correct torque on audio cartridge mounting hardware. These types of screws need a torque between 0.06Nm to 0.4Nm. The Tochinchi RTD30CN supports a range of 0.04Nm - 0.3Nm which is perfect for my needs. The torque driver is very well built and is accurate to 3% of the set value. It comes with a certificate of calibration. The torque values are easy to set. The driver's coupler supports ¼" power bits and is about 4" long without a bit installed. The handle is non-magnetic. The coupler is slightly magnetic but is not magnetized. Non-magnetic stainless steel bits are your best bet for use when torquing cartridge mounting hardware. Since audio cartridges have magnets, you should to be a little careful. This driver is a great value, is well built, and is simple to set and use.

good tool for small torque

These work nicely, depending on your application.

Tohnichi is the largest manufacturer of torque wrenches in Japan, So you can count on the quality! These are great for the small tight jobs like gun smithing and electronics, It’s the tool all your friends want to borrow

Received from Japan (Tonichi) faster than scheduled. Good product, too.

Bought this to work on a Digital cinema movie projector. This specific model and brand was recommended by the projector manufacturer during a training class. Instructions are a little unclear as how to set the torque, but I did finally figure it out. Since it will only be used to work on my projectors, I'll really never have to adjust it again. I probably could have used something way less expensive from Harbor Freight, but since I'm working on a $50k movie projector, I figured I'd go ahead and spend the money. Be aware that this ships from Japan, so it takes several weeks (almost a month in my case) to get it.

Very nice torque wrench. Works as expected. USPS delivered to wrong address so seller shipped replacement overnight - can't ask for better than that.

まあ、そこまでする事は無いんですけどね。ラジコン組み立てに使ってます。必ず同じ締め付け具合になるので。ま、現地でいじる時は使ってませんけど。自己満足です。

Nice tool, the only down is that the handle is small and hard to grab on

Esta marca japonesa está especializada en aparatos dinamométricos de alta calidad.El destornillador dinamométrico que nos ocupa es un claro ejemplo de esta calidad. Es muy fácil de calibrar y es adecuado para mecánica de precisión en aparatos delicados. Su rango es de 20 a 120 cN.m.Para su uso es preciso emplear puntas largas o bien puntas normales con adaptador.Recomendado totalmente.

使いやすい。ビットをもっと手軽に色々入手できると良い。細くて長いを数種類、とか。

信頼できるメーカー、商品。
