STAR-M has been making woodworking drill bits in Miki City, Japan's historic home of blacksmithing and hardware, since 1923, when founder Motoji Kobayashi began crafting bits in a small workshop. The STAR-M trademark followed in 1940, and the company is still led by the Kobayashi family today. It celebrated 100 years of drill making in 2023.
From the Short Machine bit of 1958 and the Impact Bit series of 1996 to today's Super Clean Cut range, STAR-M manufactures its drill bits, carbide-tipped bits and custom-made drills at its factories in Miki. Japanese carpenters and woodworkers choose them for clean, accurate holes and edges that last, and STAR-M bits are now used around the world, including in the USA under the WoodOwl brand.

Star-M 601 range of Drill Bits are precision milled and cuts cleaner than any drill bit you'll ever encounter. This is achieved by having the pin perfectly in the center of the drill, which will always create a centred hole. These super clean cut drill bits are extremely efficient in both cross cut as well as with the grain.
Designed specifically for soft materials like wood, hard wood, rubber, acrylic board and PVC that can otherwise be problematic to drill, the knife-like flutes of the Star-M bits deliver precise cuts in even more fibrous materials, such as bamboo.
Hooked spurs clear any remaining waste from the perimeter of the cut, these are followed by semi-circular wings that incise a little deeper to part the waste from the surrounding material. A curved cutting edge then planes the waste out and sends it up the flutes.
For plastics use a low speed setting, for fibrous materials use your highest speed setting, and in both cases introduce the bit to the material gradually.

I've got a large collection of Star-M brad point bits from JTA. They are best suited to a drill press where you can get the full benefit of their precision.
Before using them for the first time I was a little skepticsl of the 1/4" hex fitting but my concerns have been fully allayed in use. They are just as accurate and well centred as a conventional round shaft.
The holes they cut are incredibly accurate to the nominated size with the bits having negligible runout.
The point tips are very well centred and sharp, making lining up a hole with a mark on your wood really easy. The cuts are exceptionally clean on both entry and exit due to the slicing action of the outer edge of the bit spirals before the bulk of the wood is removed by the rest of the bit face.
Another upside to these bits arises if you need to drill many holes of varying diameters in quick succession. All the bits up to 12mm are the same length and those from 13-19 are too. This makes table height adjustments on a drill press much less frequent whilst maintaining the workpiece an optimum distance from the drill bit. This is partularly useful if you're drilling blind holes with depth stops.
Overall I am very happy with these drill bits and highly recommend them for precision work.

Cleanest cutting drill bits I’ve ever used, my go to

A joy merely to look at!

Absurdly good. I go outside just to drill clean holes for fun.

I need a really sharp drill bit for drilling tuner holes in highly figured exotic timber without the chance of tear out, this bit is perfect, I’ll definitely be buying more. ⭐️

Neat

I love this extremely well made, compact pouch for my Star woodworking drill bits. Fine craftsmanship both with pouch and bits.

These are the best drill bits that I have ever had the privilege of owning and using. I do a lot of pieced lathe work and these bits provide the cleanest entry and exit holes, resulting in minimal sanding and clean-up. These bits have saved me approximately one hour in time for every pierced project I make. I'm going to purchase the larger set and the "half" set in the next little while.

Great little roll to pair with the drill bits. Organises and protects then well in the tool box. Has little pouches for drill stops and other small attachments
M
This is my second drill roll
I use it exclusively for the fractional bits and take both to my men’s shed every week thereby ensuring that I can find a sharp bit in the right size immediately instead of scrabbling through a drawer full of blunt unsized bits
B
Very very impressive performance in Australian hardwood.
C
Just as clean as the standard sizes excellent quality and usual speedy delivery by JPA
N
Super sharp and perfect for my job. Will be buying more

We use a lot of plywood and find these drills perfect for cutting plug holes also we cut long end grain holes and this drill works better than anything else we have tried.
P
These are by far the best and sharpest drill bits I have ever used, a clean cut every time!

I've used these drill bits for sometime in making musical instruments. I know no finer drill bit
G
These are beautiful bits to use. I am currently working a project requiring clean and very accurate holes. These bits really do the job. The brad point is easy to position accurately and tracks precisely. The very sharp cutting surface make a very clean hole with very little breakout. The bits are a bit shorter than you might expect, but this has not yet been a problem in my project.

very good

Best cutting drill ever. Never before seen holes as clean.

Admittedly this purchase was higher quality and price than many of my tools, but the results were excellent. My project required 40 holes to be drilled in plywood and I was aiming for good presentation. The plywood was very prone to splintering, but this drill cut extremely cleanly. The flutes really are knife-like.

Just the ticket for all my Super Clean-Cut Drills by STAR-M all fit nice and snug, with great protection. Also highly recommend the STAR-M Drills.
