Product Description


Milled in Europe EU and exported to Australia, these black oxide drill bits are available in metric and imperial sizes. They are the perfect addition to any workshop and are great for use in portable and battery-operated drills. We have tested these drill bits to repeatedly drill holes in up to 8mm heavy-duty steel plate.

Our core business is the distribution of industrial tools both nationally and overseas. You can be confident in browsing the products that you are viewing quality tools.  These black oxide coated tools applied to high-speed drill bits provide excellent lubricity and anti-corrosive properties.

All of our black oxide drill bits have a point angle of 135 degrees for drilling into hardened steel.  Metal drill bits with 118 degree angled tips are predominantly for wood and softer materials.  which is the most suited for drilling into hardened materials such as stainless steel with portable drills. The other 118 degree specification often referred to is better suited to softer materials such as wood.


We distribute a range of black oxide drill bit products to metal fabrication businesses and workshops nationally. We stock single bits or quantities for our customers. Currently, we offer 5, 10 or 20-bit packs that our customers depending on their requirements can purchase individually or complement their existing drill bit sets.


Half and Fully ground drill bits refer to metal manufacturing processes. They exist to enable more efficient drilling in hard and soft materials.
Half ground drill bits are roll forged and ground down the length of the flutes. Fully ground is as the name refers, ground from top to bottom of the drill bit.

At Zip Tie Guy we’ve found a niche industrial supplies manufacturer who produces good quality products. Check out our range and purchase a set, you won’t be disappointed.
