Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

I received many kind words from various people.<\/p>\n

To be honest, just because it\u2019s been 10 years doesn\u2019t mean anything to me personally; I\u2019m just going about my work as usual.<\/p>\n

Still, it\u2019s really just a small milestone, so it\u2019s a good way to look at it as a day to express gratitude to everyone.<\/p>\n

We will continue to operate as usual, so we appreciate your continued support.<\/p>\n

\"Thank<\/p>\n

\n

But that's beside the point.<\/p>\n

Tips for Drilling Straight Holes<\/h3>\n

Do you think it's possible to drill a straight hole?<\/p>\n

Is it possible to drill a hole exactly as intended?<\/p>\n

The answer isNO<\/strong><\/span>That's it.<\/p>\n

That said, an experienced operator who knows the machine\u2019s quirks might be able to do it.<\/p>\n

However,Even just drilling a straight hole the usual way is a real challenge.<\/span><\/strong><\/span>That's it.<\/p>\n

Depending on the soil conditions, there is a high likelihood that the drill bit will bend even when drilling a hole only about 10 meters deep.<\/p>\n

To be honest, since I was on the management side myself, I didn't really understand how difficult it was to drill straight holes.<\/p>\n

Now I really feel it in my bones\u2014it\u2019s tough these days, lol.<\/p>\n

That said, I\u2019ll just ask our employees to do it (lol)<\/p>\n

\"Drainage<\/p>\n

When it comes to things like catch basins or tie-rod drilling (drilling horizontally to create holes at specified locations),<\/p>\n

Since the position of the hole is predetermined, this makes it particularly difficult.<\/p>\n

Anyone who does curved drilling operations is truly a pro among pros! I really think they're amazing.<\/p>\n

This is a technique that involves using a gyro sensor for verification, but it can\u2019t be done by an inexperienced operator.<\/p>\n

 <\/p>\n

So, here's the trick to digging straight, for starters.<\/p>\n

Let's start with the machine.<\/p>\n

\"Rotary<\/p>\n

This is the guide section at the tip of the rotary percussion device.<\/p>\n

Since the casing sits on top of this, it keeps rubbing against it more and more.<\/p>\n

This causes the drill bit to wobble.<\/p>\n

The newer it is, the less variation there will be.<\/p>\n

\"-<\/p>\n

Next is the original part of the swivel mechanism.<\/p>\n

That's a shank rod, isn't it?<\/p>\n

If there's even a little wear here, the lead will slip down.<\/p>\n

The parts here are crazy expensive, lol.<\/p>\n

 <\/p>\n

Next is drilling. When it comes to precision, we tend to be a bit more cautious, but,<\/p>\n

Drill the holes as usual.<\/span><\/strong><\/span>That's it.<\/p>\n

It is precisely during drilling operations that require high precision that you can identify the machine's errors by drilling as you normally would.<\/p>\n

Does this machine turn left? Does it turn right? Does it go to the top left?<\/p>\n

It\u2019s important to identify that pattern, so just drill as you normally would.<\/p>\n

That said, it\u2019s also heavily influenced by the soil type, soThis is it!!<\/span><\/strong><\/span><\/p>\n

I can't say that.<\/p>\n

It\u2019s important to use a drilling machine with a drilling method suited to the soil conditions.<\/p>\n

 <\/p>\n

\"Improve<\/p>\n

Next,Setting the drilling diameter larger than the specified size will improve accuracy.<\/span><\/strong><\/span><\/p>\n

For a hole diameter of \u03c690, drilling with a \u03c6115 bit will ensure the hole is straight.<\/p>\n

And finally,Drilling with the largest machine possible will take the accuracy up another notch.<\/span><\/strong><\/span><\/p>\n

However, this depends on site conditions, such as whether machinery can be brought in or not.<\/p>\n

Conversely, the smaller the aircraft, the greater the risk of the hole warping, and<\/p>\n

In the worst-case scenario, it might get jammed and won't come out... Digging holes is a complex business.<\/p>\n

 <\/p>\n

I think anyone can dig a hole about 10 meters deep. (It might not be perfectly straight, though.)<\/p>\n

However, once you go beyond that, you\u2019re definitely entering the realm of the professionals.<\/p>\n

Even our employees sometimes encounter extremely difficult rock formations when drilling holes that are only about 15 meters deep.<\/p>\n

We\u2019re going through a lot of trouble to drill these holes. But even this hard work is part of the drilling process that leads to the next step.<\/p>\n

It makes me happy to think that my level is going to keep going up like this.<\/p>\n

\"Master<\/p>\n

I\u2019m writing as if I know everything, but I actually have master teachers who are like sages in various fields! lol<\/p>\n

When I'm stuck, I call my mentors and ask for their guidance.<\/p>\n

When I'm stuck, my mentors tell me about every possibility they can think of.<\/p>\n

I'm so grateful to my mentors! Thank you so much!<\/span><\/strong><\/span><\/p>\n

I'm just freely sharing those teachings (techniques) with everyone across the country without asking anyone's permission, lol.<\/p>\n

Eventually, I\u2019d like to introduce companies with experienced teams as well.<\/p>\n

 <\/p>\n

See you later.<\/p>","protected":false},"excerpt":{"rendered":"

joining a major construction company specializing in slope stabilization, I went independent at the age of 32. With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/high-precision-drilling-norimen\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-10-10 23:50:54","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2018\/03\/0957656c4dc6d339652a2a8c2cbda465.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6128","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=6128"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6128\/revisions"}],"predecessor-version":[{"id":60875,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/6128\/revisions\/60875"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/6137"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=6128"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=6128"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=6128"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
