As a business, we will naturally assume there is a requirement of concentricity or equal wall thickness unless we are told otherwise, for example, if the application is simply for fluid flow

You could argue that we are over-engineering the machining and this is at the expense of our competitiveness within the industry. However, we believe in giving the customer the very best that can be achieved and ensuring that they do not encounter any unexpected issues further down the production process.

At Hone-All we are committed to the belief that simpler is better when it comes to supply chains. Most people know Hone All for our practical services in advanced honing, boring, and CNC machining. However, we’re also dedicated to trouble shooting, project management, and ironing out supply chain creases.

Drill wander is a major feature of all deep hole drilling and deep hole boring machinery and service provision. This is where the drilled hole will start perfectly on centre and although the bore will be completely straight, the exit will be off-centre by an amount relative to the length of the hole drilled.

Specialist services such as deep hole boring, deep hole drilling and honing are a black art to some and still slightly grey for others.

Modern apprenticeships do not cover such skill sets and even the traditional apprenticeships from decades ago only ever covered honing or grinding in a minimal format.

Deep Hole Boring is a highly specialised process and is used for the drilling of bores above ø20mm internal diameter. A variety of forms can be utilised within the process including blind bores, counter bores, flat bottomed bores etc. depending on the application.

You may think that they all say that, and they probably do.

Therefore, it’s worth taking two or three minutes to understand our justification for claiming that you will not find better – or at least understand our approach and the way we do business. It’s the only way for us, and it has delighted thousands of customers throughout the years. We believe we have the winning formula of professionalism, advanced technology and industry expertise and it’s all at your disposal.

Producing blind bores into precision machined components, and responsibly quoting for them, should always result in more questions for the customer. As much as time is short during our busy working days, and these queries often result in a little lost time, it’s always worth investigating at the design stage whether the form required suits the process needed to produce it or will require a non-standard tool.

If so, you’re certainly not alone. 

Drilling, honing and boring costs are notorious for being something of an arcane secret for people who aren’t ‘in the know’ about the process involved. We have attempted to shed some light on the world of pricing in our latest downloadable e-book: The Guide To Deep Hole Drilling, Boring & Honing Costs. You can download a copy by clicking here.

Honing is one of those subcontract services which often suffers an unfairly bad reputation!

Covered in the apprenticeships of old, it's always the honing machines that bring either the wry smile or comical grimace when people visit as if they were lucky enough to go through a full apprenticeship it was either one of their favourites or the hated machine that just “had to be used to pass the exam”.

A deep hole is defined by the depth-to-diameter ratio and every hole larger than a ratio of 10:1 is considered deep. There are lots of applications for deep hole drilling across many industries, with the origins tracing back to gun barrels. Deep hole drilling is used in different materials and can help achieve a tight diameter, straightness, and a perfect surface finish.
