Lathe jig to, stainless steel deep drilling
From Japan
On 2016-12-14 06:14:16
The square bar of SUS304 was no problem to 30mm through-holes as a spacer. Stainless steel, thought it was impossible or because it is just a high-speed steel Han Dreamer, was able to clean drilling. Rotation speed management and cutting oil is required. That's common drill of less than 4.0mm, but is easy to bend where you are with the drill bit, Han Dreamer did not bend without distortion. Example: It was not from being inserted only up to the middle and put a round bar of 2.8mm after opening the 2.8mm through the pilot holes, once established a through-hole in the Han Dreamer 3.0mm, high-speed steel 3.0mm Gasun Narri entering for lathe year. One day, when you open the 3.0mm through-hole of the only in the drill as well, high-speed steel 3.0mm for the lathe did Mase Sasari only halfway. Once established a through-hole in the Han Dreamer 3.0mm, but high-speed steel is now sticks like, play is now in terrible state wobble there is more than 0.1mm. MonotaRo's to In cooperation with F.P. tool, we want to sell Han Dreamer or machine reamer in 0.1mm increments. Since cutting hole not distorted, is under hole also want to open in the reamer.

To buy HR2.0 · HR3.0 · HR4.0, does not still using only HR4.0, I feel until the blade diameter Φ4.0mm was good also in the number four blade. Open properly prepared hole, but we used the HR4.0 does not come neatly discharged chips. (Processing under hole 3.8mm · hole depth 20mm · Material: iron, blade length is I think the depth of 40mm, so the hole is that it is common for no 20mm any problem.) In addition, it has become a "with food length (mm) 1 (± 0.3)," but, measured was the place 0.5mm in digital calipers (± 0.05) was only no. Really with food length is 1mm: if it is 45 degrees, but it should be a principle under hole 2.1 ~ 3.9mm, 0.5mm: in the case of 45 degrees will become 3.1 ~ 3.9mm. Course length was also the difference with food HR2.0 · HR3.0. Blade diameter of the separately-Nazi titanium coating drill at a local hardware store was 3.8mm. (3.9mm Series is a high amount of money difference. It is close to double the amount in Stock.) At the same case is due the same as HR2.0 · HR3.0, the longest HR4.0 the total length in which I bought If you have most reduced case length, does not fit in the case. Case shape is not using the things of the same shape as the Nazi-drill, we handle a longer case also fits reasonably HR4.0. Because there is a thing that is left over, we re-covering the label seal by replacing the case. Even in MonotaRO made long neck end mill is so, but I want you to refrain case has a short case towards. The Han Dreamer did not have a blade cover made of resin rubber. I think that it is a paper for the rust, but It did not peel off clean even when the paper that had been rolled so thin in the blade diameter 2 · 3 · 4mm carefully peeled off, end mills also those of less than shank size 4.0mm 4.0 because it does not have a cutting edge only cover for mm, there is that the cover is off in the case that it Toka shank size 3.0mm. Because how not, are marked to buy a drill blade cover at a local hardware store. It is a Nazi and NS Tool's case I want to adopt as a reference.

Adjusting holes
From Japan

Although brown spots can be seen with dots on the rake face when looking at product pictures, rusting has occurred as shown in the photo. It seems that removal of iron powder during processing is insufficient to induce rust. Since there is no effect on the cutting edge, I think that there is no choice if I consider the price.

Dial gauge mounting hole
From Japan

Since I have not used it yet, the satisfaction level is 3. I am planning to use it for the hole of SUS 304. When I measured it with a caliper, the tip of the reamer was 7.9 mm. Probably because it is used only once, it was decisive of purchase that it was cheap in price But just how strong it is? I do not understand without trying it.

Correction of roughness of knock pin hole of mini motorcycle engine
From Japan
On 2011-11-14 19:00:25
Processing was done without problems. However, because there is no taper at the tip bite portion, rattles are attached to the entrance part of the hole, but I think that it is a good product when considering cost performance.
