Harvey Tool Miniature Drills, Counterbores & Reamers
Explore Harvey Tool holemaking tools for small holes, controlled hole geometry and finishing operations. Browse miniature drills, material-specific drills, spotting tools, counterbores and reamers. Start with the required hole diameter and depth, then consider the work material, bottom shape, tolerance and coolant access for each step of the process.
Miniature Carbide Drills
Compare small-diameter drills by diameter, flute length and overall length. Confirm the dimension system and the required drilling depth on the actual listing. Choose the geometry and coating for the material, with chip evacuation considered as part of the setup.
Material Specific Drills
Browse dedicated aluminum, prehardened-steel and hardened-steel drill families. Match the exact material and hardness to the selected series. Review flute length, coating and the manufacturer’s drilling guidance before assuming a tool suits a different alloy or condition.
Spotting & Center Drilling
Compare spotting drills with combined drills and countersinks. These tools create different entry or center features. Match point angle, diameter and geometry to the planned operation and follow the selected drill’s guidance for any spotting step.
Deep Hole Coolant-Through Drills
Use the deep hole category to compare coolant-through drills by diameter and working length. Confirm the required coolant delivery and drilling procedure for the selected series. Machine capability, holder connection and chip evacuation all affect the usable setup.
Flat Bottom Drills & Counterbores
Compare flat bottom drills with flat bottom and corner radius counterbores. Select the tool for the required operation and bottom geometry. Long reach counterbores provide additional access; check the neck and cutting dimensions against the part.
Miniature Reamers
Explore straight flute, metric straight flute and right-hand spiral reamers for finishing prepared holes. Match the reamer size and geometry to the hole specification and work material. Use the manufacturer’s recommended preparation and allowance for the chosen tool.
Composite & PCD Drilling Options
Compare brad point and double-angle composite drills with PCD diamond-tipped double-angle tools. Identify the laminate, reinforcement and entry or exit requirements before selecting a geometry. These families have distinct constructions and application recommendations.
Prepare for Thread Milling
Plan the hole diameter, depth and bottom clearance around the selected thread and milling process. For appropriate applications, compare combination drill/thread mills with separate drilling and threading tools. Follow the exact tool’s sequence and programming guidance.
Check Size, Depth & the Holding System
Confirm whether the drawing specifies drilled, reamed or threaded dimensions. Compare usable tool length, shank size and holder clearance as an assembly. Review the exact part’s stock information before scheduling the job around an expected delivery.
Holemaking Tools Questions
- What is the difference between a drill and a reamer?
- A drill creates a hole, while a reamer is used to finish a prepared hole to the required size and condition. Follow the selected reamer’s preparation and allowance recommendations.
- Is a flat bottom drill the same as a counterbore?
- They are separate tool families. Select by the intended operation, existing hole condition and required bottom geometry, and confirm what the particular tool is designed to cut.
- Should every hole be spotted first?
- Follow the selected drill’s guidance. When spotting is specified, use an appropriate spotting geometry and procedure; do not assume one point angle or sequence is suitable for all drills.
- How do I choose a drill for a deep hole?
- Check the required drilling depth, usable length, material application and coolant requirements. Use the selected series’ drilling procedure and confirm that the machine and holder can support it.
- Are there separate drilling tools for composites?
- Yes. The linked families include composite brad point, composite double-angle and PCD double-angle drills. Match the exact construction and geometry to the material and hole requirements.
- Where can I find the holemaking specifications?
- Use the Harvey Tool interactive catalog and the selected product’s drawing for dimensions and application details. Confirm the exact part and current stock information on the Suncoast listing.
