BTA Drilling Services in Canada

BTA Drilling is a deep hole drilling process that utilizes specialized drilling tools run on a long drill tube. BTA is a much more efficient method of drilling compared to traditional twist drills and gun drilling.

Size Range: .875" to 8.00" diameters

Our state-of-the-art drilling machines, coupled with sophisticated manufacturing processes, have given us the reputation for being an industry leader in BTA drilling. Differentiating technology combined with the best BTA drilling equipment on the market allows us to drill incredibly straight holes at extreme diameter to depth ratios. Capable of BTA drilling concentric holes up to 40 ft in length while guaranteeing OD to ID Concentricity of .010 TIR, we have the knowledge and skills to make your project a success. We are very strong in offset / eccentric BTA deep hole drilling. We are able to guarantee .020 positional tolerances at extreme depths.

Our focus is in reducing our customers net cost by preventing the need to purchase oversize material and reduce the amount of subsequent machining to finish a part. Our precision drilling service can provide a significant cost savings when working with exotic alloys. No need to chase an ID for those projects with tight wall thickness tolerance when you request our .010 TIR guarantee.

Our in-house engineering department has the knowledge and experience to design custom form tooling for unique bore configurations that cannot be accomplished with conventional tools. Experience the difference of working with a deep hole drilling company that puts their passion into every project no matter the size or complexity. Contact us online today.
