ACE SAW AND SUPPLY’S


(W)HOLE STORY

Carbide Tipped Hole Saws       Plastics Laminates and Fiberglass

Materials Cut

For cutting Plastics, Plastic Laminates, Fiberglass, Fiber Reinforced Plastics, Plastic-Fiberglass Composite Material.

Utilization

Drilling holes in flat sheeting, curved surfaces like tank and or piping.

Materials Used, Manufacturing Process, and Dimensional Tolerances

Hole saw bodies are machined from ASTM 4130 bar stock. Tolerances are maintained to +/- .001” on diameter and .003” TIR
Micro grain, high impact carbide, cryogenically treated teeth are silver soldered to the hole saw body.

Sizes Available

Standard sizes kept in stock are from ¾ in diameter to 4-1/2 inches in diameter in ¼ inch increments with a cut depth of 1-3/4 inches.

Since we turn the bodies from bar stock custom diameters and custom cut depths are available on request. 

Drive Mandrel and Center Drill

Ace Saws Standard hole saws above 1-1/4 in diameter have a threaded arbor 5/8 -13 hole.
The standard mandrel shanks offered are ½, 3/8 or ¼ inch diameter.
The standard center drill sizes are ¼ and 3/8 in diameter.
 
These can all be modified as requested on a custom application.

Tooth Count, Tooth Grind Geometry and Finish and Material Testing

The number of teeth used for different diameters, the tooth grind geometry and grind finish are part of Ace Saws proprietary information, however with past experience Ace saw is able to achieve the following objectives.

A clean cut chip free cut
No sheet de-lamination when cutting composite materials.
Plug formation that readily releases from the hole saw body
Long tool life between sharpenings.

Ace Saw will test Clients material samples with their hole saw in their Los Alamitos facility if any of the above objectives are not considered satisfactory. They will find a solution to minimize Client’s overall drilling costs per hole. The solutions found may require a change in the tooth count, the grind geometry, hole saw cutting speed and hole saw cutting feed into the material.

Equipment Recommended for Drilling Holes with Ace Hole Saws

Most users prefer to use a standard electric or pneumatic drill motor with say a 3/8 or ½ in chuck.  Larger diameter hole saws should be run at lower speeds to keep the tip velocity with the required range.  Consequently variable speed drives are an advantage if the user is going to use many different size hole saws.

Ace Saws hole saws has been used with stationary equipment like drill presses or CNC machining centers.

Three Flute Drills

Ace Saw offers their proprietary three flute drills for cutting holes with diameters between 3/8 to1-1/4 in.  These too are custom made for any specified diameter and tolerance.

The advantage of using three flute drills is that it eliminates the plug completely that particularly with the smaller diameters holes might not release cleanly from the hole saw. They can also be used on conventional or CNC drilling and milling machines. 

Hole Saw Maintenance and Service

Ace Saw provides a 72 hour turn around to return hole saws shipped to them for service.

Typically Ace Saw’s Hole saws can be sharpened 6 to 8 times before they require re-tipping, hole saw bodies can be re-tipped at least 6 times and often more depending on the depth of cut requirements.

Drilling Costs per Hole

The cost of a hole saw is only part of the total drilling cost per hole.  The other factors that need to be considered are:

            Costs of product scrapped by holes drilled with a poor finish
            Costs of repairing Holes drilled with a poor finish
            The time to drill each hole correctly
            The number of holes that can be drilled before the tool is dull.
The number of times a hole saw can be sharpened and the cost of sharpening.
            The number of times a hole saw van be re-tipped and the cost of re-tipping
