1. Ocean PENETRATOR COBALT Twist Drill Bits - Taper Shank

Click thumbnails to view larger images
These Cobalt drills are the newest drill bits on offer, and are made specifically for CNC Beam Drill Lines. We tested this drill bit in early August 2006 and drilled 490 holes in 1 hour. We also drilled more than 500 holes and the drill was still drilling holes at less than 8 seconds per hole. Click here to see the Ocean PENETRATOR Cobalt Drill Bit video.

The Ocean PENETRATOR Drill Bits even arrive from the factory pre-sharpened to 175 degrees with a split point. Unfortunately we are currently only able to offer the following diameters - 9/16", 11/16", 13/16" and 15/16". They feature Cobalt Steel - longer life - in our recent testing we were able to drill well over 500 holes before resharpening was required. Dramatically reduces costs. Pre-sharpened to 175 degrees with raised tip - this is the ideal recommended tip for structural steel. No need for pre-sharpening. It requires only a single-stage drill grinding procedure. This simplifies the resharpening and saves resharpening time More than 500 holes between sharpenings (see video) Should yield 50,000 holes per drill bit - Click here to view video. Faster Drilling feed rates - The Ocean PENETRATOR works best at 7.1 in/min of feed rate - almost 20% faster than regular twist drill bits. This results in faster drilling times. Chipbreaker point - eliminates long stringy chips that clog swarf bins and fly all over the shop. It requires only a single-stage drill grinding procedure and saves resharpening time. No grinding required on the exit of the hole with properly sharpened drills - dramatically reduces costs Direct access to sophisticated technical support. Ocean Machinery provides you with direct access to the manufacturers' tech support hot-line. Pricing - 13/16" costs $160.00 Call Ocean Machinery at 1-800 286 3624 today to order your drill bits for your Ocean Clipper, Ocean Avenger or other CNC Drilling Line.

The Big Debate - Insert Drill Bits VS. Twist Drill Bits

We at Ocean Machinery are often asked by our customers what drill bits should they use - twist drill bits or insert bits? While we have always recommended and still recommend Twist Drill Bits, there have been significant strides in the recent past with regard to insert spade bits that are worth noting....

Insert Drill Bit (Spade Drill Bit ) Advantages	Insert Drill Bit (Spade Drill Bit )Disadvantages
Savings – You avoid having to spend $10,000 on a drill grinder. Convenience - They always have a perfectly ground structural point. Simplicity - They can just be discarded when dull and they are cheap to replace - around $30 every 800 - 1000 holes. Convenience - Nobody has to learn the art of sharpening drill bits.	Cost - Insert Drill require holders for each drill size and you require at least two holders of each size. Cost - Insert bits definitely leave a burr on the exit of the hole, especially on lighter profiles and the fabricator must spend money on labor and consumables to grind the exit of the hole. Cost - If an insert breaks, the tool holder will be damaged and will have to be replaced - replacing tool holders is expensive. Cost - If the Torx head holding the insert is stripped you have to replace the tool holder - replacing tool holders is expensive. Cost – see worked costing example below.
Twist Drill Bit Advantages	Twist Drill Bit Disadvantages
Savings – You do not need to grind the exit of the hole – save on non value added activity. Savings – Twist drill bits cost less than 1/10th the cost of insert drill bits – see worked costing example below. Convenience - It only takes a couple of hours to train an operator to be able to sharpen drill bits. Savings and Convenience - you can purchase twist drill bits from any vendor – you are not locked into a particular supplier. Savings – No matter how badly you dull a drill point it can always be resharpened – in some cases you can also resharpen a broken drill bit.	Inconvenience - You need to train an operator how to sharpen drills. Cost – you have to purchase a $10,000 drill grinder.

COSTING - Twist Drill Bits Vs. Insert Drill Bits

Costing Example

Lets compare Twist Drill Bits and Insert Drill bits in the real life fabrication situation. We will just look at one example – 13/16” (the most commonly drilled hole diameter)

Lets first look at the cost of using twist drill bits that need to be resharpened

A. Twist Drill bits

13/16” (18mm) Twist drill bit is typically $140.00
Need to have a minimum of two drill bits of each size so we can change out and re-sharpen one drill bit while the other one is drilling
Operator gets 300-500 holes per sharpening – let’s use 300 to be conservative
Operator gets approximately 100-150 sharpenings per drill bit – let’s use 100 to be conservative
Therefore – 300 x 100 = 30,000 holes per drill bit
Two drill bits = 2 x $140 = $280 – provides 60,000 holes

A. Cost to drill 60,000 holes is $280 consumable cost (plus the $10,000 capital of the sharpener which gets amortized over the life of the machine - There are many Rush 250 grinders in fabrication shops that are in excess of 10 years old).

Now lets look at the cost of using Insert Drill Bits

B. Insert Drill Bits

13/16” holder is typically $200.00
13/16” T/A drill insert is typically $30.00
Need to have a minimum of two holders of each size so we can change out the inserts while we are drilling with the other holder
Operator gets 800 - 1,000 holes per insert – let’s use 800 to be conservative
Therefore we require 2 holders ($400) and 75 inserts ($2,250) to drill 60,000 holes

B. Cost to drill 60,000 holes is $400 + $2250 = $2650 consumable cost

Observation

The consumable cost is 9 TIMES more expensive using insert drill bits

The above example is true for all drill sizes, but the cost differential increases with the size of the drill bit. This also does not take into account any replacement holders that need to be ordered when

The holder is damaged when an insert breaks while drilling
The holder is no longer usable when the insert screws strip off or seize
And it does not take into account the cost of grinding the exit of the hole.

All of the above situations do occur in real life. Also note that as the drill diameter increases the cost of the holders can go up to as much as $800 each.

It doesn’t take too much math to realize that in significantly less than one year you will have completely paid off the drill grinder from your savings in consumable costs and you will be well on your way to becoming a low cost producer.

So what drill bit does Ocean Machinery recommend for beam lines?

We believe that for now, based on current pricing from the various suppliers, the customer is better off with good quality twist drill bits and a good quality sharpener. Any one of the brands above will do a great job (Ocean Penetrator, Nachi or Cleveland).

Of course, training an operator to sharpen drill bits properly is important, and we do a thorough job during the installation of the Avenger. We have trained hundreds of operators who totally get it and are able to resharpen bits in less than a couple of minutes.

To assist our operators with their drill sharpening techniques we host online drill sharpening video tutorials on our Web Site.
