BAT Gundrilling Svc
Deep, straight holes in metal and plastic, drilled to your drawing in Santa Clara.
Acerca de
BAT Gundrilling Svc runs a precision deep-hole drilling shop at 2730 Scott Boulevard in Santa Clara, in the industrial blocks between the Caltrain line and Central Expressway, with a second facility a short drive away on De La Cruz Boulevard. Max Gomez is the owner. The shop is small, in the range of two to ten people, and its customers are the industrial and semiconductor-equipment makers that fill this part of Santa Clara County.
Deep-hole drilling, explained
Gundrilling is a machining process for holes that are far deeper than they are wide: cooling passages, hydraulic and air lines, and weight-reducing bores in blocks, shafts and plates. A conventional drill wanders after a few diameters of depth; a gundrill, fed with high-pressure coolant through the tool, keeps the hole straight and the surface finish clean over lengths a general machine shop cannot reach.
BAT Gundrilling describes itself as a job shop, which means it works to the customer's drawing rather than making a product of its own. Parts arrive from other machine shops and from equipment builders, get their deep holes drilled, and go back for the rest of the machining.
Sending a job to the shop
Bring a drawing or a model that calls out hole diameter, depth, straightness and position tolerance, and say what the material is: ferrous metals, non-ferrous metals and plastics behave differently under the tool. Ask for a lead time at quoting, since a job shop schedules around what is already on the machines, and ask whether the part can be drilled from one side or must be flipped. If the part comes from another shop, agree who owns the datum surfaces before it ships.
Where the parts come from
Most work comes from Santa Clara, San Jose, Sunnyvale, Cupertino, Milpitas, Campbell, Mountain View and Los Altos, the manufacturing belt of Santa Clara County. Both sites sit north of downtown Santa Clara near the Highway 101 and San Tomas corridors, convenient for a courier run.

Servicios
Típico de este tipo de negocioSingle-flute gundrilling of long, straight, small-diameter holes in blocks, shafts, manifolds and plates, where an ordinary twist drill would wander off centre or leave a rough bore.
Deep holes in steel, stainless, aluminium, brass and copper alloys, with tooling and coolant pressure adjusted to the material so the hole stays true over its full depth.
Gundrilling of engineering plastics such as acetal, nylon and PEEK for manifolds and fixtures, taking care with heat build-up so the bore keeps its size and finish.
Drilling to the tolerances, positions and depths called out on a customer's print or model, on parts supplied by other machine shops or by equipment builders in Santa Clara County.
Additional machine capacity at a nearby De La Cruz Boulevard site, useful when a job needs a second setup or a customer wants a shorter turnaround on a batch.

Preguntas frecuentes
Típico de este tipo de negocioWhat is gundrilling and when do I need it?
Gundrilling makes holes whose depth is many times their diameter, typically past the point where a standard drill drifts. If a drawing calls for a long coolant passage, hydraulic line or lightening hole with a straightness or finish requirement, a gundrilling shop is the usual route.
What should I send with a request for quote?
A drawing or model with hole diameter, depth, position and straightness tolerance, the material and its condition, the quantity and the date needed. Most shops also want to know whether the part arrives rough or finished, since that decides how it can be fixtured.
Can the shop drill from both sides to reach a long hole?
Often, but it depends on the part and the tolerance. Ask whether the shop can hold alignment when a hole is drilled from two ends, and whether a single long pass is possible on its machines instead.
How long does a gundrilling job usually take?
It depends on what is already running. A job shop schedules around current work, so ask for a quoted lead time and confirm it again when the parts ship to the shop, especially for a batch.
Antes de contratar
- Send a drawing that states hole diameter, depth, position and straightness tolerance.
- State the material and whether the part arrives rough-machined or finished.
- Ask for a written quote with lead time and how the parts will be inspected.
- Confirm who owns the datum surfaces if the part is coming from another shop.
- Ask whether the hole is drilled from one side or two and what that means for alignment.
